Explanation:

In chemical kinetics (a subfield of Chemistry, which is part of Natural Science), an increase in temperature provides more reactant molecules with energy greater than or equal to the activation energy. This leads to a higher frequency of effective collisions between reactant molecules, thus increasing the rate of the reaction. So the correct option is the one that states temperature increase leads to an increase in reaction rate.

Answer:

b. increases
