Question

For the reaction 2A(g) B(g), the equilibrium constant is K_p = 0.76. A reaction mixture initially contains 4.0 atm of gas (P_A = 2.0 atm and P_B = 2.0 atm). You may want to reference. Section 15.7 while completing this problem. Which statement is true of the reaction mixture? ?The reaction mixture will proceed toward products. The reaction mixture is at equilibrium. The reaction mixture will proceed toward reactants ? It is not possible to determine from the information given the future direction of the reaction mixture.

Explanation / Answer

Ans Part A . A) The reaction mixture will proceed towards products.

Qp = [B] / [A]2

Qp = (2.0) / (2.0)2

Qp = 0.5

Since Qp < Kp , the reaction will proceed in the direction of formation of products .
