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 :
Solution
<p>(A) $\mathrm{\Delta U=q-p\Delta V}$</p>
<p>(B) $\mathrm{\Delta G=\Delta H-T\Delta S}$</p>
<p>(C) $\mathrm{\Delta S=\frac{q_{rev}}{T}}$</p>
<p>(D) $\mathrm{\Delta H=\Delta U+(\Delta nRT)}$</p>
<p>Hence, (B) and (C) relations are correct.</p>
