Verified Solution • 2025–26 Session moderate

Which of the following relations are correct?

(A) $\mathrm{\Delta U=q+p\Delta V}$

(B) $\mathrm{\Delta G=\Delta H-T\Delta S}$

(C) $\Delta \mathrm{S}=\frac{q_{rev}}{T}$

(D) $\mathrm{\Delta H=\Delta U-\Delta nRT}$

Choose the most appropriate answer from the options given below :

Accepted Answer

(A) $\mathrm{\Delta U=q-p\Delta V}$

(B) $\mathrm{\Delta G=\Delta H-T\Delta S}$

(C) $\mathrm{\Delta S=\frac{q_{rev}}{T}}$

(D) $\mathrm{\Delta H=\Delta U+(\Delta nRT)}$

Hence, (B) and (C) relations are correct.
