Q. 2

For the reaction

Answer :

• In the viewpoint of thermodynamics, Equilibrium can be explained by the following mathematical equation


∆G = G + RTlnQ which comes down to ∆G = G + RTlnK and then to


G = - RTlnK (as at Equilibrium ∆G is zero and Kc is = Q )


And k = e-G /RT (by taking antilog on both sides)


therefore, when G > 0, which means positive, it will give a negative K value


( eG /RT attains a negative value for a positive G ) and hence K < 1.
