Electrochemistry question

2023 · Q98

NEETChemistryElectrochemistryMCQ+4 / −1

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

Assertion A : In equation ΔrG=−nFEcell\mathrm{\Delta_rG=-nFE_{cell}}Δr​G=−nFEcell​, value of ΔrG\mathrm{\Delta_rG}Δr​G depends on n.

Reason R : Ecell\mathrm{E_{cell}}Ecell​ is an intensive property and ΔrG\mathrm{\Delta_rG}Δr​G is an extensive property.

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

  1. A
    Both A and R are true but R is NOT the correct explanation of A.
  2. B
    A is true but R is false.
  3. C
    A is false but R is true.
  4. D
    Both A and R are true and R is the correct explanation of A.

Correct answer: D

$$\mathrm{\Delta_rG=-nFE_{cell}}$$

$\mathrm{E_{cell}}$ is an intensive property and $\mathrm{\Delta_r G}$ is an extensive property as it depends on number of $\mathrm{{e^\Theta }}$ transferred in cell reaction.
