 The rate law for a reaction  \mathrm{aA + bB \rightarrow cC}  is given by  \mathrm{k[A]^{2}[B]} . Which among the following may increase the rate of reaction?

Option: 1

Increase in temperature 


Option: 2

Increase in the concentration of A

Clearly from the rate law given, the order of reaction with respect to A & B is positive integer. Hence, increasing the concentration of A and B shall increase the rate of reaction. Further, the increase in temperature increases the frequency of collision og reacting particles, thus increases the rate of reaction.
