Which expression correctly relates the activation energy of the reverse reaction (

E_{a,\,\text{rev}}

) to the activation energy of the forward reaction (

E_{a,\,\text{fwd}}

) and the enthalpy change of the overall reaction (

\Delta H

)? (a)

E_{a,\,\text{rev}} = E_{a,\,\text{fwd}} + \Delta H

(b)

E_{a,\,\text{rev}} = E_{a,\,\text{fwd}} - \Delta H

(c)

E_{a,\,\text{rev}} = \Delta H - E_{a,\,\text{fwd}}

(d)

E_{a,\,\text{rev}} = E_{a,\,\text{fwd}} + |\Delta H|
