Thermodynamics question

2022 · 28 Jul · Shift 2 · Q2

JEE MainChemistryThermodynamicsMCQ+4 / −1
Given below are two statements: One is labelled as Assertion A\mathbf{A}A and the other is labelled as Reason R\mathbf{R}R Assertion A : The reduction of a metal oxide is easier if the metal formed is in liquid state than solid state. Reason R\mathbf{R}R: The value of ΔGΘ\Delta G ^\ThetaΔGΘ becomes more on negative side as entropy is higher in liquid state than solid state. In the light of the above statements, choose the most appropriate answer from the options given below
  1. A
    Both A and R are correct and R is the correct explanation of A
  2. B
    Both A and R are correct but R is NOT the correct explanation of A
  3. C
    A is correct but R is not correct
  4. D
    A is not correct but R is correct
