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 0.22 M CH₄,0.67 M CO₂and 1.3 M H₂O.Which of the following statements is true concerning this system?

Question

Quizplus · Accepted Answer

To determine if the reaction will shift in the direction of products or reactants, we need to calculate the reaction quotient Q and compare it to the equilibrium constant Kc. Qc = [CO₂]^1[Cu]^4[H₂O]^2/[CH₄]^4[CuO]^4 Plugging in the given concentrations, we get: Qc = (0.67)^1(1.3)^2/(0.22)^4 = 12.5 Since Qc is larger than Kc, the reaction will shift in the direction of reactants to reach equilibrium. Therefore, the correct choice is D) The reaction will shift in the direction of reactants.
