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 of a reaction increases with increase in temperature and becomes nearly double for every ${10}^{\circ }$ rise in temperature. The effect can be represented quantitatively by Arrhenius equation,
$k=A{e}^{\frac{-E_a}{RT}}$
Where, $E_a$ is the activation energy of the reaction and A represents the frequency factor.
