The reaction profile for a reversible chemical reaction is shown below.

Reaction profile

Which row in the table below correctly identifies the arrow representing the activation energy of the reverse reaction, Ea(reverse)E_{\text{a}}(\text{reverse})Ea​(reverse), and the arrow representing the enthalpy change of the forward reaction, ΔH(forward)\Delta H(\text{forward})ΔH(forward)?

Ea(reverse)E_{\text{a}}(\text{reverse})Ea​(reverse) is represented by Arrow 2; ΔH(forward)\Delta H(\text{forward})ΔH(forward) is represented by Arrow 3.

Ea(reverse)E_{\text{a}}(\text{reverse})Ea​(reverse) is represented by Arrow 1; ΔH(forward)\Delta H(\text{forward})ΔH(forward) is represented by Arrow 3.

Ea(reverse)E_{\text{a}}(\text{reverse})Ea​(reverse) is represented by Arrow 2; ΔH(forward)\Delta H(\text{forward})ΔH(forward) is represented by Arrow 4.

Ea(reverse)E_{\text{a}}(\text{reverse})Ea​(reverse) is represented by Arrow 1; ΔH(forward)\Delta H(\text{forward})ΔH(forward) is represented by Arrow 4.
