Problem
A sealed vessel contains the gaseous reaction 2 A ⇌ B at equilibrium. Without changing the temperature, additional A(g) is injected so that its partial pressure instantly doubles while the partial pressures of all other species remain unchanged. Describe the immediate sign of ΔG and indicate whether the net reaction will proceed in the forward or reverse direction as the system moves toward a new equilibrium.
