Answer:
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction without itself getting consumed in the reaction as it helps in decreasing the activation energy. Thus, rate of reaction also increases.
A positive catalyst helps in increasing the rate of a chemical reaction whereas a negative catalyst decreases the rate of a chemical reaction.
Whereas when we increase the temperature then collisions between the particles increases due to increase in kinetic energy. Hence, rate of reaction increases with increase in temperature.
Thus, we can conclude that out of the given options adding a positive catalyst will increase the rate of a chemical reaction.
