Enthalpy is equal to
(a)$\mathrm{TS}+\mathrm{PV}+\Sigma \mu_{\mathrm{i}} \mathrm{n}_{\mathrm{i}}$
(b)$\mathrm{TS}+\Sigma \mu_{\mathrm{i}} \mathrm{n}_{\mathrm{i}}$
(c)$\sum \mu_{\mathrm{i}} \mathrm{n}_{\mathrm{i}}$
(d)$\mathrm{PV}+\Sigma \mu_{\mathrm{i}} \mathrm{n}_{\mathrm{i}}$
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
G = Σμᵢnᵢ and H = G + TS, so H = TS + Σμᵢnᵢ (b).
