Ratio of rates =( text rate of 2 text nd reaction / text rate of 1 text st reaction ) =((2.5)7 r/(2)7 r) =4.77=5

Q. Two reactions proceed at $3 5^{\circ} C$ 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 $10 5^{\circ} C$ .

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

Q. Two reactions proceed at 35∘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∘C.

Ratio of rates = rate of 1 st reaction rate of 2 nd reaction ​ =(2)7r(2.5)7r​ =4.77=5
