Evaluate multistep reaction mechanisms, identify intermediates and catalysts, and reason about rate-determining steps.
Interpret multistep energy profiles, activation barriers and molecularity.
Deduce reaction orders and rate equations from experimental initial-rate data.
Use rate and concentration-time graphs to identify reaction orders and interpret half-lives.
Calculate rate constants and their units, use rate equations and assess consistency across experimental data.
Use Arrhenius plots and temperature-dependent rate constants to calculate activation energy.
Investigate concentration, pressure and surface area while identifying and controlling experimental variables.
Explain why temperature changes reaction rates, distinguishing collision frequency from the fraction of successful collisions.
Construct and interpret Maxwell–Boltzmann energy distributions and explain the role of activation energy.
