उत्तर
The rate constant of a reaction is nearly doubled with a 10° rise in temperature. However, the exact dependence of the rate of a chemical reaction on temperature is given by the Arrhenius equation.
k = `Ae^(-E_a/(RT))`
Where,
A = Arrhenius factor or the frequency factor
T = Temperature
R = Gas constant
Ea = Activation energy
