(6 marks) An easy way to analyse the amount of CO2 in a gaseous mixture of CO2 and CO is to pass the gaseous mixture through an aqueous solution that contains excess Ba(OH)2. The CO2 will react yielding a precipitate of BaCOs but the CO does not react (you will learn why in higher classes). The aforementioned method was used to analyse the equilibrium composition of the gas evolved when 1.77 g of CO2 reacted with 2.0 g of graphite...

14.89 A gaseous mixture containing 1.00 mol each of CO, H2O, CO2, and H, is exposed to a zinc oxide-copper oxide catalyst at 1000°C. The reaction is CO(g) + H2O(g) + CO2(g) + H2(g) and the equilibrium constant K is 0.58 at 1000°C.
