Question

How does catalyst and temperature effect the rate if the reaction?

Answer 1

Hey !!!   This is called the activation energy. A catalyst provides an alternative pathway for the reaction, that has a lower activation energy. ... Adding a catalyst or increasing the temperature will increase the number of particles in this area and so indicates the rate will increase.

Answer 2

the substance  in whose presence the rate of a chemical reaction changes ,without  causing any chemical change to it is called a catalyst .
