A reaction mixture initially contained 0.1 mol/L of reactant A and 0.2 mol/L of reactant B. When a catalyst was added, the rate of conversion of A and B to the product increased significantly. Calculate the new equilibrium concentration of reactant B if the equilibrium constant of the reaction is 0.1 and the initial equilibrium concentration of the product is 0.05 mol/L. Assume that the catalyst does not change the equilibrium constant.
