Answer: Catalyst and Temperature
Explanation: Catalyst is the subsatnce which is used to increase the rate of reaction by altering the route to reach towards the product thereby decreasing the activation energy.
Thus catalyst does not alter anything else but it will just increase the rate of the reaction.
Temperature is also used to increase the rate of reaction. If temprature of the system is increased , it will enhance the number of collisions between the particles and thus increasing the rate of the reaction.
