Q.
Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R:

Assertion A : In equation $Δ_{r} G = - n F E_{cell}$ , value of $Δ_{r} G$ depends on $n$ .

Reason R : $E_{cell}$ is an intensive property and $Δ_{r} G$ is an extensive property.

In the light of the above statements, choose the correct answer from the options given below. [2023]

1 A is true but R is false.

2 A is false but R is true.

3 Both A and R are true and R is the correct explanation of A.

4 Both A and R are true and R is not the correct explanation of A.

Ans.
(4)

$Δ_{r} G = - n F E_{cell}$

$E_{cell}$ is an intensive parameter but $Δ_{r} G$ is an extensive thermodynamic property and the value of $Δ_{r} G$ depends on $n$ .

Solution

1 A is true but R is false.

2 A is false but R is true.

3 Both A and R are true and R is the correct explanation of A.

4 Both A and R are true and R is not the correct explanation of A.

Ans.
(4)

$Δ_{r} G = - n F E_{cell}$

$E_{cell}$ is an intensive parameter but $Δ_{r} G$ is an extensive thermodynamic property and the value of $Δ_{r} G$ depends on $n$ .
