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) ↔ COCI₂ (g) ∆Hᵒᵣₓₙ = -109 kJ/molyan
(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?
