Q. Two first order reactions proceed at $\text{25}^{\text{o}} \text{C}$ at the same rate temperature. Coefficient of the rate of the first reaction is $\text{2}$ and that of second reaction is $\text{3}$ . Find the ratio of the rate of these reaction at $\text{75}^{\text{o}} \text{C}$ .

Solution:

Temp coefficient $=\frac{R_{T} + 10 ^\circ C}{R_{T}}$

$\mathrm{R}_{\mathrm{T}+\Delta \mathrm{T}}=\mathrm{R}_{\mathrm{T}}(\mathrm{TC})^{\frac{\Delta \mathrm{T}}{10}}$

Rate of reaction

Solution

$=7.59$
