in a chemical reaction, what role does a catalyst play?\na. consumes all reactants\nb. decreases activation energy\nc. increases activation energy\nd. has no effect on activation energy
Answer
Brief Explanations:
A catalyst is a substance that speeds up a chemical reaction by providing an alternative reaction pathway with a lower activation energy. It is not consumed in the reaction and does not affect the amounts of reactants or products in the long - run equilibrium.
Answer:
B. Decreases activation energy
