One mole of a non-ideal gas undergoes a change of state ( 2.0 a t o m , 3.0 L , 95 K ) → ( 4 a t m , 5 L , 245 K ) with a change in internal energy, Δ E = 30.0 L a t m . The change in enthalpy, Δ H , of the process in L atm is

Question

One mole of a non-ideal gas undergoes a change of state ( 2.0 a t o m , 3.0 L , 95 K ) → ( 4 a t m , 5 L , 245 K ) with a change in internal energy, Δ E = 30.0 L a t m . The change in enthalpy, Δ H , of the process in L atm is, 40.0, 42.3, 44.0, not defined, because pressure is not constant

MARKS App · Accepted Answer

Δ H = Δ E + Δ ( P V ) Δ H = 30 + 4 × 5 - 2 × 3 = 44 L a t m
