Question

The $\Delta H$ value of the reaction $H_2 + Cl_2 \rightleftharpoons 2HCl$ is $-44.12 \,kcal$. If $E_1$ is the activation energy of the products, then for the above reaction

• A. $E_{1}>E_{2} $
• B. $E_{1} < E_{2} $
• C. $E_{1}=E_{2} $
• D. $\Delta H$ is not related to $E_1$ and $E_2$

Answer 1

Answer: (A)

Because reaction is exothermic
