In equation $\Delta_rG=-nFE_{cell}$, value of $\Delta_rG$ depends on $n$.
Reason: $E_{cell}$ is an intensive property and $\Delta_rG$ is an extensive property.
A
Both A and R are true and R is the correct explanation of A
B
Both A and R are true but R is NOT the correct explanation of A
C
A is true but R is false
D
A is false but R is true
Explanation
$\Delta_rG$ is extensive and scales with $n$, while $E_{cell}$ is intensive.
Detailed Solution
Free energy is an extensive property, and $E^o_{cell}$ is an intensive property. $\Delta_rG$ depends on the $n$, which is the number of electrons transferred in the reaction: $\Delta_rG=-nFE^o_{cell}$
