Rates of reaction
6.1.1 Define the term rate of reaction.
6.1.2 Describe suitable experimental procedures for measuring rates of reactions.
TOK: The empirical nature of the topic should be emphasized. Experimental results can support the theory but cannot prove it.
6.1.3 Analyse data from rate experiments.
Collision theory
6.2.1 Describe the kinetic theory in terms of the movement of particles whose average energy is proportional to temperature in Kelvin.
6.2.2 Define activation energy, Ea.
6.2.3 Describe the collision theory.
6.2.4 Predict and explain, using the collision theory, the qualitative effects of particle size, temperature, concentration and pressure on the rate of a reaction.
6.2.5 Sketch and explain qualitatively the Maxwell–Boltzman energy distribution curve for a fixed amount of gas at different temperatures and its consequences for changes in reaction rate.
6.2.6 Describe the effect of a catalyst on a chemical reaction.
6.2.7 Sketch and explain Maxwell– Boltzmann curves for reactions with and without catalysts.
