JEE MAIN - Chemistry (2023 - 29th January Evening Shift - No. 3)
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 :
A and B only
B and C only
C and D only
B and D only
Explanation
(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.
