Solution

The correct option is A
True

The energy and speed of the molecules of reactant increases as the temperature increases. The number of molecules with threshold energy increases which increases the number of effective collisions. Hence the rate of the reaction increases. Therefore, the rate of the reaction will be maximum in the test tube with hot water.
