Detailed explanation-1: -The energy and speed of the molecules of reactant increases as the temperature increases. The number of molecules with threshold energy increase which increases the number of effective collisions. Hence the rate of the reaction increases with the increase in the temperature.
Detailed explanation-2: -With increase in temperature, rate of reaction always increases due to increase in number of molecules having energy greater than activation energy.
Detailed explanation-3: -In general, increasing the concentration of a reactant in solution, increasing the surface area of a solid reactant, and increasing the temperature of the reaction system will all increase the rate of a reaction. A reaction can also be sped up by adding a catalyst to the reaction mixture.
