Answer» Temperature, enthalpy and entropy are state functions For both reversible and irreversible isothermal expansion of an ideal GAS, change in internal energy and enthalpy is zero For a reaction in which `Delta n_(g) = 0`, entropy change is not always zero The entropy change associated with reversible isothermal expansion of an ideal gas is equal to 2.303 R `"LOG"_(10) (P_(1))/(P_(2))` Solution :(a) T, H, S are state functions (b) `Delta T = 0 rArr Delta E = Delta H= 0` (c ) even if `Delta n_(g) = 0, S` may change (d) Reversible isothermal, `Delta S = (q_("rev"))/(T) = R "ln" (V_(2))/(V_(1)) = R "ln " (P_(1))/(P_(2))`
