WebFeb 18, 1999 · Reaction rates are roughly doubled when the temperature increases by 10 degrees Kelvin. This means the rate can be quadrupled if the temperature is raised by 20 degrees Kelvin. It should be clear that if you can increase reaction rates by increasing temperature you can decrease reaction rates by lowering the temperature. WebAug 14, 2024 · If the temperature changes the rate changes so the reaction enthalpy change makes a difference. The other difference is more subtle: as a reaction progresses the product concentrations increase and the reverse reaction rate increases The difference between the activation energies is the energy change of the reaction.
