Question
(a) What is a catalyst? (b) What is the difference between a homogeneous and a heterogeneous catalyst? (c) Do catalysts affect the overall enthalpy change for a reaction, the activation energy, or both?
Step 1
It is not consumed in the reaction, meaning it can be used repeatedly. In mathematical terms, a catalyst is a substance that increases the rate constant of a reaction, thereby increasing the speed of the reaction. Show more…
