For the reaction, A(g) + B(g) → C(g) + D(g), Δ Hº and Δ Sº are, respectively, –29.8 kJ mol –1 and –0.100 kJ K –1 mol –1 at 298 K. The equilibrium constant for the reaction at 298 K is:
Text Solution
Verified by ExpertsThe correct answer is:
A
Δ Gº = Δ Hº – T. Δ Sº = –29.8 + 298 × (0.1) = –29.8 + 29.8
Δ Gº = 0
apply relation between Δ Gº & K eq
Δ Gº = –RT λ n K eq
∴ K eq = 1
