Solved: CHEMISTRY Question for NEET

NEET CHEMISTRYMedium

Given below are two statements: Assertion (A): In the equation, $\Delta_rG = -nFE_{cell}$ , value of $\Delta_rG$ depends on $n$ . Reason (R): $E_{cell}$ is an intensive property and $\Delta_rG$ is an extensive property.

(A) is False but (R) is True.

Both (A) and (R) are True and (R) is the correct explanation of (A).

Both (A) and (R) are True and (R) is not the correct explanation of (A).

(A) is True but (R) is False.

Step-by-Step Solution

According to the relation $\Delta_rG = -nFE_{cell}$ , the Gibbs free energy change ( $\Delta_rG$ ) depends on the number of moles of electrons transferred ( $n$ ). This is because $E_{cell}$ is an intensive property (independent of the amount of substance), while $\Delta_rG$ is an extensive thermodynamic property (dependent on the amount of substance, represented by $n$ ). Thus, Reason (R) is true and correctly explains Assertion (A).
