Consider the following reaction and its equilibrium constant: 4 CuO(s) + CH₄(g) ⇌ CO₂(g) + 4 Cu(s) + 2 H₂O(g) K_c = 1.10
A reaction mixture contains 0.20 M CH₄,0.70 M CO₂and 1.5 M H₂O.Which of the following statements is TRUE concerning this system?

Question

Quizplus · Accepted Answer

To determine the direction in which the reaction will shift, we need to compare the reaction quotient (Q) to the equilibrium constant (K). Q = ([CO₂] * [Cu]^4 * [H₂O]^2) / [CH₄]^4 Substituting the given values into the equation, we get: Q = (0.70 * 1.5^2) / 0.20^4 = 109.38 Since Q > K, the reaction will shift in the direction of reactants to reach equilibrium. Therefore, the correct answer is D.

Consider the Following Reaction and Its Equilibrium Constant: 4 CuO(s)
