Q. Two reactions proceed at $35^{\circ} C$ at the same rate, the temperature coefficient of the rate of first reaction is $2.0$ and of the second $2.5$. Find the approximate ratio of rates of these reactions at $105^{\circ} C$.

Chemical Kinetics

Solution:

Ratio of rates $=\frac{\text { rate of } 2 \text { nd reaction }}{\text { rate of } 1 \text { st reaction }}$
$=\frac{(2.5)^{7} r}{(2)^{7} r}$
$=4.77=5$
