question 109

Multiple Choice

An equilibrium mixture of CO, O₂, and CO₂ at a certain temperature contains 0.0010 mol L^-1 CO₂ and 0.0015 mol L^-1 O₂. At this temperature, K_c equals 1.4 × 10² L mol^-1 for the reaction: 2CO(g) + O₂(g) ⇌ 2CO₂(g)
What is the equilibrium concentration of CO?

• A)4.8 × 10^-6 mol L^-1
• B)8.5 × 10^-3 mol L^-1
• C)9.3 × 10^-2 mol L^-1
• D)3.1 × 10^-1 mol L^-1
