Q.
If value of any Thermodynamic parameter is zero than both the options, one with plus sign and other with
negative should be selected.
Column I (Reactions)
Column II (Signs of Thermodynamic parameter)
A
Isothermal expansion of ideal gas
P
$\Delta H = + , \Delta S = + \Delta G = -$
B
Any substance at its normal freezing point and $1 atm$ pressure, $A _{( S )} \rightleftharpoons A _{(l)}$
Q
$\Delta H = - , \Delta S = + \Delta G = -$
C
Condensation of any gas into liquid
R
$\Delta H = - , \Delta S = + \Delta G = -$
D
A reaction which is spontaneous at all the temperatures
S
$\Delta H = - , \Delta S = - \Delta G = +$
T
$\Delta H = + , \Delta S = + \Delta G = +$
