Question

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. $ ~
• D. $~>4$

Answer 1

Answer: (A)

$~>2$

Answer 2

The temperature coefficient is the ratio of two velocity constant having the difference of $10^{\circ} C$.
Temperature coefficient $=\frac{K_{t}+10}{K_{t}}$
For most of the reaction its value lies between 2 and 3 .
