Which of the following statement(s) is/are false?
(a) All adiabatic processes are isoentropic (or isentropic) processes
\( \mathrm{P} \)
(b) When \( \left(\Delta G_{\text {system }}\right)_{T, p}0 \); the reaction must be exothermic
W
(c) \( d G=V d P-S d T \) is applicable for closed system, both \( P V \) and non-PV work
(d) The heat of vaporisation of water at \( 100^{\circ} \mathrm{C} \) is \( 40.6 \mathrm{~kJ} / \mathrm{mol} \). When \( 9 \mathrm{gm} \) of water vapour condenses to liquid at \( 100^{\circ} \mathrm{C} \) and \( 1 \mathrm{~atm} \), then \( \Delta S_{\text {system }}=54.42 \mathrm{~J} / \mathrm{K} \)
