As per your syllabus, + eqn 5.7, the ENTHALPY H is defined as which quantity?
AH = U − pV
BH = U + pV — and at constant pressure ΔH = q_p
CH = TS only
DH = q + w
Answer & Solution
Correct answer: B. H = U + pV — and at constant pressure ΔH = q_p
As per your syllabus, eqn 5.7, H = U + pV.
ΔH = q_p (heat absorbed at constant pressure).
H is a state function because U, p, V all are.
