A Catalyst: I. Lowers Activation Energy

A catalyst:
I. lowers activation energy
II. provides an alternate reaction pathway
III. is consumed in the reaction and therefore does not appear
In the chemical equation of each mechanism
IV. speeds a reaction
V. is heterogeneous if it is in a different phase than the reactants
