Equilibrium Shift with Increased Concentration of Reactant

Medium General Chemistry Chemical Equilibrium

In a closed system at equilibrium, the following reversible reaction occurs:

2A(g) + 3B(g) <=> 4C(g)

At a certain temperature, the equilibrium constant (K_c) for this reaction is measured to be 6.0. If the concentrations of A, B, and C at equilibrium are found to be 2.0 M, 1.0 M, and 3.0 M respectively, which of the following statements correctly describes the shift in the equilibrium position if the concentration of B is increased?

The equilibrium will shift to the left to produce more A and B.

The equilibrium will shift to the right to produce more C.

The equilibrium will not change at all.

The reaction will favor the formation of products and increase the concentration of A.
