The rates of reaction invrease with increase of temperature because

Answer»

activation ENERGY of the REACTION molecules decreases
kinetic eriergy of the product molecules increases
the fraction of the REACTING molecules possessing an· energy equal to the activation energy
the collisions between molecules decrease

SOLUTION :With increase in temperature, tehe factor `._eE_a//RT`which gives fraction of molecules with energy increases and hence `E_a` increases.
