Vedclass · Accepted Answer

Standard free energy change of a cell is an intensive property.

Vedclass · Answer

(C) $1$. Standard cell potential $(E^{\circ}_{cell})$ is an intensive property because it does not depend on the amount of matter present in the system.$2$. Electrode potential depends on the concentration of the electrolyte solution as described by the Nernst equation $(E = E^{\circ} - \frac{RT}{nF} \ln Q)$.$3$. Standard free energy change $(\Delta G^{\circ} = -nFE^{\circ}_{cell})$ is an extensive property because it depends on the number of moles of electrons $(n)$ transferred,which is related to the amount of substance.$4$. Electrical work done in a galvanic cell is equal to the decrease in Gibbs energy $(W_{elec} = -\Delta G)$.$5$. Therefore,the statement that the standard free energy change is an intensive property is false.

$LIST$-$I$ (Cell)	$LIST$-$II$ (Use/Property/Reaction)
$A$. Leclanche cell	$I$. Converts energy of combustion into electrical energy
$B$. Ni-Cd cell	$II$. Does not involve any ion in solution and is used in hearing aids
$C$. Fuel cell	$III$. Rechargeable
$D$. Mercury cell	$IV$. Reaction at anode $Zn \rightarrow Zn^{2+} + 2e^-$
