An Equilibrium Mixture of CO, O₂, and CO₂ at a Certain

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

Definitions:

Profit Maximization

The process or strategy of adjusting production and operational variables to achieve the highest possible return or profit.

Variable Costs

These vary with output. When output rises, variable costs rise; when output declines, variable costs fall.

Break-Even Points

The production level or point in sales at which total revenues equal total expenses, resulting in neither profit nor loss.

Shutdown Point

The level of operations where a company's revenue from goods or services sold just covers its variable costs, beyond which it becomes more cost-effective to halt production.
