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. \( \Delta G = \Delta H - T \Delta S \)

Hint:

In thermodynamics, always verify the sign conventions in equations. For example, the correct relation between enthalpy (\( \Delta H \)) and internal energy (\( \Delta U \)) is \( \Delta H = \Delta U + P \Delta V \).
