1. Consider the following reaction in chemical equilibrium at 500 K. CO(g) +2H2(g) <-----> CH3OH(g) in one experiment, 0.15 mol CO and 0.3 mole H2 are initially placed in a 1.5 L flask. and at equilibrium 0.1187 mol of CH3Oh was present. a. What is the concentration of each species present when equilibrium is reached? b. What is the value of Kc for this reaction at 500K?
