A catalyst increase the rate of a chemical reaction by providing a path that?
- raise the activiation energy
- increase the temperature
-
lowers the activation energy
- increase the concentration
The correct answer is: C
Explanation
The rate of a reaction can be increased by adding a suitable catalyst.
A catalyst is a substance which increases the rate of a chemical reaction but it is not used up (remains chemically unchanged at the end).
It provides an alternative reaction pathway of lower activation energy.
