Explain how temperature affects rate using Maxwell-Boltzmann distributions.

In the subtopic Factors affecting reaction rate, this AQA A-Level Chemistry 7405 learning objective focuses on explain how temperature affects rate using Maxwell-Boltzmann distributions. It belongs to Kinetics, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include temperature, rate. Maxwell-Boltzmann distribution. means a statistical distribution that describes the energy distribution of particles in a gas, illustrating how temperature affects reaction rates Avoid the mistake of students often confuse activation energy with the overall energy change of a reaction, thinking it is the same as the enthalpy change; instead, activation energy is the minimum energy required for a reaction to occur, not the total energy change. To clarify, remember that activation energy is a barrier that must be overcome for reactants to transform into products. Use the Maxwell-Boltzmann distribution to visualize how temperature affects the number of particles with energy equal to or greater than the activation energy, thus increasing the reaction rate For exam answers, use Maxwell-Boltzmann distribution curves to explain how increasing temperature raises reaction rates by increasing particle energy and collision frequency
