Answer
K is 9.1 so the reaction will shift to the left side to reach equilibrium.
Step-by-step explanation
3A(g) + 4B(s) ↔ 2C(g) + 2D(g) K = 9.1
From the equilibrium given, the equilibrium constant K is 9.1 so the equilibrium will shift to the left side favoring reactants formation.
This is because if K is greater than 1, it means the concentrations of the products are greater than those of the reactants and the equilibrium will shift to the reactant side to favor the reactants.
