In a reversible reaction, the forward reaction is exothermic and has an activation energy of $+30\,\text{kJ mol}^{-1}$. The reverse reaction follows a mechanism that is precisely the reverse of the forward reaction mechanism. Which statement about the activation energy for the reverse reaction is correct?
- AThe activation energy for the reverse reaction is equal to $-30\,\text{kJ mol}^{-1}$.
- BThe activation energy for the reverse reaction is greater than $0\,\text{kJ mol}^{-1}$ but less than $+30\,\text{kJ mol}^{-1}$.
- CThe activation energy for the reverse reaction is equal to $+30\,\text{kJ mol}^{-1}$.
- DThe activation energy for the reverse reaction is greater than $+30\,\text{kJ mol}^{-1}$.
