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
Correct answer is C
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.
