In a reversible reaction, carbon monoxide gas and hydrogen gas are mixed to produce methanol gas (CH3OH). The enthalpy change of this reaction is AH = 90 kJ mol A mixture of 0.360 moles of CO and 0.640 moles of H2 were allowed to reach equilibrium at 150°C in a 10 dm' sealed container. At equilibrium the mixture contained 0.120 moles of CH,OH. (a) Calculate the K for this reaction (to 1.d.p). (10 marks) Similarly to Ko, K is an...
