(b) Lower temperature generally results in ______________ reaction rate.

(c) Lower activation energy results in _____________ reaction rate.

(d) In multistep reactions, ________________ are produced but they don’t appear in the overall equation.

(e) The rate-determining step is the ________________ step of a multistep mechanism that determines the overall rate of the reaction.

(f) _______________ lower the activation energy of the reaction by providing a completely different mechanism of the reaction.

(g) Enzymes are generally __________________ catalysts that exist in the same phase as the reactants.

(h) An ________________ site is the specific location where a substrate undergoes catalytic reaction in an enzyme.
