The reaction

2 NO(g) + Br2(g) ⟺ 2NOBr(g)

has an equilibrium constant of 116.6  at 25°C. If Mickey Mouse starts with the reaction mixture PNO = 0.300, PBr2 = 0.225, PNOBr = 0.855 at 25°C, predict what will happen as the reaction proceeds towards equilibrium. The initial partial pressures are given in atm.

a) More reactants will form

b) More products will form

c) The reaction is already at equilibrium

d) It is impossible for the process to come to equilibrium from these starting conditions

e) Not enough information is given
