In this topic,Student should be able to :
a) Explain and use the terms: rate of reaction; activation energy; catalysis; rate equation; order of reaction; rate constant; half-life of a reaction; ratedetermining step.
b) Explain qualitatively, in terms of collisions, the effect of concentration changes on the rate of a reaction.
c) Explain that, in the presence of a catalyst, a reaction has a different mechanism, i.e. one of lower activation energy.
d) Describe enzymes as biological catalysts which may have specific activity.
e) Construct and use rate equations of the form Rate = k[Am[Bn with special emphasis on: i) Zero order reaction ii) 1 st order reaction iii) 2 nd order reaction
f) Show understanding that the half-life of a first-order reaction is independent of initial concentration and use the half-life to calculate order of reaction.
g) Calculate the rate constant from the given data. h) Name a suitable method for studying the rate of a reaction, from given information.
