Q. The activation energy for most of the reactions is approximately 50 kJ $mol^{- 1}$. The value of temperature coefficient for such reactions is
A) > 2
B) >3
C) <1
D) >4
Explanation
(a)
The temperature coefficient is the ratio of two velocity constants having the difference of $10℃$.
Temperature coefficient
$= \frac{k_{t} + 10}{k_{t}}$
For most of the reactions its value lies between 2 and 3.
