IB Chemistry HL 2.2.11 Hl Rate Constant K Questions

Use real HL exam questions to calculate the rate constant from rate data, derive its units from reaction order and explain its temperature dependence.

Exam points

Calculate the rate constant k from a stated rate equation together with measured rate and reactant concentrations, reporting the correct value and units.
Deduce the units of k from the overall reaction order and the units of rate and concentration.
Explain or interpret how k varies with temperature, distinguishing this from activation energy, reaction enthalpy and concentration effects.
