Question

The relation between enthalpy change ∆H and internal energy
change ∆E of a system is:
(a) ΔΕ= ΔΗ+PAV
(b) ΔΕ= ΔΗ+RT Δ Η
(c) ΔΗ= ΔΕ+RT. ΔΗ
(d) ΔΗ= ΔΕ-ΡΔV​

Answer 1

Answer:

Enthalpy is a state function whose change indicates the amount of heat transferred from a system to its surroundings or vice versa, at constant pressure. The change in the internal energy of a system is the sum of the heat transferred and the work done.
