If Δ H is the change in enthalpy and Δ E the change in internal energy for a gaseous reaction then

Question

If Δ H is the change in enthalpy and Δ E the change in internal energy for a gaseous reaction then, Δ H is always greater than Δ E, Δ H Δ E only if the number of moles of the products is greater than the number of the reactants, Δ H is always less than Δ E, Δ H Δ E only if the number of moles of the products is less than the number of moles of the reactants

MARKS App · Accepted Answer

The change in enthalpy and the change in internal energy for a gaseous reaction is given by Δ H = Δ E + Δ n g R T If Δ n = - v e than Δ H Δ E .
