Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:Assertion A: In the equation , the value of depends on .Reason R: is an intensive property and is an extensive property.In the light of the above statements, choose the correct answer:
- ABoth A and R are true and R is the correct explanation of A
- BBoth A and R are true and R is not the correct explanation of A
- CA is true but R is false
- DA is false but R is true
Solution & Step-by-step Explanation
1. Assertion A is true: Gibbs free energy change () depends on the amount of substance reacting (number of electrons ), so its value changes if the stoichiometry of the reaction is multiplied by a factor.2. Reason R is true: (standard electrode potential) does not depend on the amount of substance, whereas does.Because is an extensive property (R), it must depend on the number of moles () involved in the reaction (A). Thus, R explains A.
