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

Question

Quizplus · Accepted Answer

Catalysts lower the activation energy and provide an alternate reaction pathway, speeding up the reaction without being consumed in the process. They can be heterogeneous if they are in a different phase than the reactants.

A Catalyst: I.lowers Activation Energy
