Q.
Which of the following graphs represents exothermic reaction?
Chemical Kinetics
Solution:
For exothermic reaction, $\Delta H=-Ve$
$\Delta H=E_{a\left(forward\,reaction\right)}-E_{a\left(backward\,reaction\right)}$
For $\Delta H$ to be $-ve$, $E_{a,b} > E_{a, f}$ which is true in graph $\left(I\right)$ only.
