Question

Which of the following relation is not correct?

• A. $\Delta H =\Delta U - P \Delta V$
• B. $\Delta U = q + W$
• C. $\Delta S_{\text {sys }}+\Delta S_{\text {surr }} \geq 0$
• D. $\Delta G =\Delta H - T \Delta S$

Answer 1

Answer: (A)

If $U + Pv$ (By definition)
$\Delta 14=\Delta U +\Delta(\text{Pr})$ at constant pressure
$\Delta H =\Delta U + P \Delta V$
