If the temperature of a reaction is increased by 10 °C, the rate of reaction often doubles. This is primarily because:
The activation energy is halved.
The concentration of reactants increases.
The number of collisions with energy ≥ Ea increases significantly.
The reaction enthalpy increases.
📝 Detailed explanation
Temperature increases the kinetic energy of particles. According to the Maxwell-Boltzmann distribution, even a small temperature rise significantly increases the fraction of molecules capable of overcoming the activation energy barrier.
