Question

If the activation energies of the forward and backward reactions of a reversible reaction are $E_a\left(f\right)$ and $E_a\left(b\right)$, respectively. The $\Delta E$ of the reaction is ...........

• A. $E_a\left(F\right)-E_a\left(b\right)$
• B. $E_a\left(F\right)+E_a\left(b\right)$
• C. $E_a\left(F\right)=E_a\left(b\right)$
• D. $-E_a\left(F\right)+E_a\left(b\right)$

Answer 1

The correct option is A $E_a\left(F\right)-E_a\left(b\right)$

As we know,
$\Delta E=E_a\left(F\right)-E_a\left(b\right)$
