Question

Consider the gas-phase reaction, 2 SO2(g) + O2(g) <=> 2 SO3(g), for which Kp = 2 at a given temperature. If the mixture is analyzed and found to contain 2.3 bar of SO2, 4.9 bar of O2 and 7.2 bar of SO3, describe the situation:

a)Q = K and the reaction is at equilibrium
b)Q > K and more products will be made to reach equilibrium.
c)Q < K and more products will be made to reach equilibrium.Q > K and more reactants will be made to reach equilibrium.
d)Q < K and more reactants will be made to reach equilibrium.

Explanation / Answer

a)Q = K and the reaction is at equilibrium
