∆H=∆U/∆E +∆n(g)RT this is the relation . And here ∆U is always same as ∆E

The relation between enthalpy and internal energy is \Delta H=\Delta U+\Delta n_g\times RT

Explanation:

\Delta H=\Delta U+P\Delta V

also PV=nRT

thus P\Delta V=\Delta n_g\times RT

\Delta H=\Delta U+\Delta n_g\times RT

where,

\Delta H =  enthalpy of the reaction

\Delta U= internal energy of the reaction

\Delta n_g = change in the moles of the reaction = Moles of product - Moles of reactant

R = gas constant

T = temperature
