°C increase in temperature. This relationship is known as the Arrhenius equation, which states that the rate constant (k) is proportional to the activation energy (Ea) divided by the product of the gas constant (R) and the absolute temperature (T):
k = A * e^(-Ea/RT)
where A is the pre-exponential factor or frequency factor, which is a constant that depends on the specific reaction and represents the number of collisions per unit time that result in a successful reaction.
The exponential term in the equation reflects the temperature dependence of the reaction rate, as higher temperatures increase the probability that reactants will collide with enough energy to overcome the activation barrier and form products.
Therefore, a small increase in temperature can have a significant effect on the reaction rate, especially if the activation energy is relatively low. For example, raising the temperature by 10°C can double the rate of a reaction with an activation energy of 20 kJ/mol, but it may have a smaller effect on a reaction with an activation energy of 80 kJ/mol.

For every 10degree celcius rise of temparature there is there Is 2 times increase in rate of reaction since teparature is incresed 5 times so 2^5 is equals to 32.
