Question

What is the effect of temperature on the rate constant of a reaction? How can this temperature effect on rate constant be represented quantitatively?

Answer 1

The rate constant is nearly doubled with a rise in temperature by 10°C for a chemical reaction.
The temperature effect on the rate constant can be represented quantitatively by Arrhenius equation,
$k = Ae^{-\frac {E_a}{RT}}$
where,
k is the rate constant,
A is the Arrhenius factor or the frequency factor,
R is the gas constant,
T is the temperature, and
Ea is the energy of activation for the reaction
