MCQ

Which of the following relation is not correct?

✓
$\Delta H =\Delta U - P \Delta V$
B
$\Delta U = q + W$
C
$\Delta S _{ syz }+\Delta S _{ suxr } \geq 0$
D
$\Delta G =\Delta H - T \Delta S$

✓

Answer

Correct option: A.

$\Delta H =\Delta U - P \Delta V$

a
If $U + P _{ V }$ (By definition)

$\Delta 14=\Delta U +\Delta( Pr )$ at constant pressure

$\Delta H =\Delta U + P \Delta V$
