Acatalyst increases the rate of a reaction without being consumed. it accomplishes this by providing another mechanism that has a lower activation energy.

The given statement is true.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, more collisions occur due to which there is rapid formation of products take place through another path.

Therefore, we can conclude that the statement a catalyst increases the rate of a reaction without being consumed. It accomplishes this by providing another mechanism that has a lower activation energy, is true.
