Equimolar amounts of Cl₂(g)Cl₂(g) and CO(g)CO(g) are injected into an evacuated, rigid container, where they react according to the equation below.
Cl₂(g) + CO(g) <=> COCI, (g) ∆H⁰ᵣₙ = -109 kJ/molᵣₙ
(a) if 7.0 g of CO(g) is consumed in the reaction with excess Cl₂(g), how many moles of COCl₂(g) COCl₂(g) are produced?
