In each of the following questions, a statement of Assertion is given

1.	In each of the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct answer as Assertion . If standard free energy change of a reaction is zero , this implies that equilibrium constant of the reaction is unity . Reason . For a reaction in equilibrium , equilibrium constant is always unity .A. If both assertion and reason are true, and reason is the true explanation of the assertion .B. If both assertion and reason are true but reason is the true explanation of the assertion .C. If assertion is true, but reason is false.D. If both assertion and reason are false .
Answer» Correct Answer - C `DeltaG^(@) = -2 *303 RT log K ` When ` DeltaG^(@) =0, log K=0 :. K=1` Hence, Assertion is correct . Correct R. For a reaction in equilibrium , the value of equilibrum constant depends upon the relative amounts of the reactants and products .
