Expert Solution

Step 1

A catalyst is a substance that increases the rate of the chemical reaction generally. It changes the mechanism of the reaction. It lowers the activation energy for the formation of the transition state or reaction intermediate. The reaction intermediate is highly unstable and decomposes to release the final product of the reaction and the catalyst. The catalyst is recovered after the reaction as it was initially. The first statement is true and the second statement is false.
