The Gibbs free energy change of a reaction and the equilibrium constant can both be used to measure the position of an equilibrium reaction and are related by the equation, ∆G° = −RT lnk Note that in the video, I use the term 'fraction of collisions with energy equal to or greater than the activation energy'. 8 Electrical conductivity of metals and semiconductors Understanding: The electrical conductivity of a semiconductor increases with an increase in temperature whereas the conductivity of metals decreases. 4. Guidance: Standard state refers to the normal, most pure stable state of a substance measured at 100 kPa. Relevant Evans2 Chem Web Notes: MSJChem is an IB chemistry teacher originally from the UK. Home Member's Area First exams 2025 Topic 1 Stoichiometric relationships An oxidising agent is so-called because it oxidises another species and therefore undergoes reduction. • A Brønsted–Lowry acid is a proton/H+ donor and a Brønsted–Lowry base is a proton/H+ acceptor. 1 Standard electrode potentials. 1 Reactivity 3. Contains practice questions and step-by-steps. The “octet rule” refers to the tendency of atoms to gain a valence shell with a total of 8 electrons. 10. topic 8. This contribution is used to pay towards the hosting fees of this website and ensures that future generations of IB chemistry students can access the site. Some atoms, like Be and B, might form stable compounds with incomplete octets of electrons. Reactivity 3. Explain how it is able to act as a Lewis base. Home Member's Area First exams 2025 topic_3_group_1_alkali_metals. 2 HL Structure 2. 8 Understandings: pH curves for neutralization reactions involving strong acids and bases have characteristic shapes and features. 8) Explain how BF 3 is able to act as a Lewis acid and state the Topic 13 Periodicity HL 13. pdf: File Size: 5786 kb Share your videos with friends, family, and the world This website features video tutorials and worksheets specifically for the International Baccalaureate (IB) Diploma Chemistry syllabus. Please note that although I MSJChem - Tutorial videos for IB Chemistry. Applications and skills: A pp lic a t i on o f ho s t–gue s t c h e m is t r y to the r e m o v al of a s pe c i This website features video tutorials and worksheets specifically for the International Baccalaureate (IB) Diploma Chemistry syllabus. Please note that this is a work in progress and will be updated on a regular basis. The reaction quotient (Q) measures the relative amount of products and reactants present during a reaction at a particular point in time. To get an idea of what is in the Member's Area, you can sign up for a Free Trial which gives you access to Structure 1. Quantitative data are obtained from measurements, and are always associated with random errors/uncertainties, determined by the apparatus, and by human limitations such as reaction times. Andrew Weng IB SL Chemistry Topic 8 Review: In depth lesson with videos and notes. This video covers the definition and properties of isotopes. Q is the equilibrium expression with non-equilibrium concentrations. 6) What must all Lewis bases have, and what must all Lewis acids be able to do? 7) Draw the Lewis structure of ammonia (NH 3). 1 Electronegativity and bonding MSJChem - Tutorial videos for IB Chemistry. A p p lica t i on s a n d skills: The general shapes of graphs of pH against volume for titrations involving strong and weak acids and bases with an explanation of their important features. 1. Additional information: Interpretation should include the intercept with the pH axis and equivalence point. 3 HL Structure 1. • Amphiprotic species can act as both Brønsted–Lowry acids and bases MSJchem – Topic 8 – Theories of acids and bases 5) Define an acid and base according to the Lewis theory. The following link is to a virtual lab website that allows you to simulate acid and base titrations and familiarize yourself with the properties of acids and bases and how they react. . 3 Understandings: Change in Gibbs energy, ΔG, relates the energy that can be obtained from a chemical reaction to the change in enthalpy, ΔH, change in entropy, ΔS, and absolute temperature, T (1. 1 Born Haber cycles . MSJChem is an IB chemistry teacher originally from the UK. Home Member's Area Videos (first exams 2025) Topic 15 Energetics HL YouTube playlist . Tutorial videos for IB chemistry. On this page, you will find links to the new syllabus topics (first exams 2025). This is the same as saying 'the fraction of particles with energy equal to or greater than the activation energy'. They have the same atomic number but different mass numbers. 1 Brønsted–Lowry acids and bases / conjugate acid-base pairs Understandings: A Brønsted–Lowry acid is a proton/H + donor and a Brønsted–Lowry base is a proton/H + acceptor. C. Understandings: The position of equilibrium corresponds to a maximum value of entropy and a minimum in the value of the Gibbs free energy. 8. Isotopes are atoms of the same element that have different numbers of neutrons. 2 Structure 2. Guidance: Calculation of reaction rates from tangents of graphs of concentration, volume or mass vs time should be covered. 3 Structure 2. 5 Structure 2. 1 Functional groups . 2 and 1. 3 Structure 1. 1 Introduction to transition elements E sse nt ial i d ea: The transition elements have characteristic properties; these properties are related to their all having incomplete d s ub-levels. Host–guest chemistry involves the creation of synthetic host molecules that mimic some of the actions performed by enzymes in cells, by s electively b i nding to specific guest species, such as toxic materials in the environment. 1 Structure 2. 2 Understandings: In a nucleophilic substitution reaction, a nucleophile donates an electron pair to form a new bond, as another bond breaks producing a leaving group. Applications and skills: Deduction of the structure of a compound given information from a range of analytical characterization techniques (X-ray crystallography, IR, 1H NMR and MS). 2). 19.
