Q23 · CSIR-NET Chemistry, December 2017

Paper: CSIR-NET December 2017 · Subject: Physical Chemistry · Chapter: Thermodynamics · Topic: Laws State Functions · Marks: 2 · Difficulty: Easy

Enthalpy is equal to

(a)$T S+P V+\sum \mu_{i} n_{i}$

(b)$T S+\sum \mu_{i} n_{i}$

(c)$\sum \mu_{i} n_{i}$

(d)$P V+\sum \mu_{i} n_{i}$

Answer

Answer: B ✓ checked by 4AB · confidence high

Explanation

Euler relation: U = TS − PV + Σμᵢnᵢ, so H = U + PV = TS + Σμᵢnᵢ (b).
