Which of the following plots represent an exothermic reaction

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
ln `K_p = -(DeltaH)/(RT) +` constant
For exothermic reaction, `DeltaH` is –ve. So when ln `K_p` is plotted against 1/T, it.s a straight line with positive slope and positive intercept.
