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

Assertion A: In equation ∆rG=−nFEcell{∆}_{r}G = - {nFE}_{cell} value of ∆rG{∆}_{r}G depends on nn.
Reasons R: Ecell{E}_{cell} is an intensive property and ∆rG{∆}_{r}G is an extensive property.

In the light of the above statements, choose the correct answer from the options given below:

Options

  1. AA is false but R is true.
  2. BBoth A and R are true and R is the correct explanation of A.
  3. CBoth A and R are true and R is NOT the correct explanation of A.
  4. DA is true but R is false.

Correct answer

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

Step-by-step solution

∆rG=−nFEcell{∆}_{r}G = - {nFE}_{cell},

In the above function Ecell{E}_{cell} is an intensive property(mass independent property)and∆rGand {∆}_{r}G is an extensive property(mass dependent property). Hence, ∆rG{∆}_{r}G depends on the number of electrons(n) transferred in the cell reaction.
