CO2(g) + H2(g) ? CO(g) + H2O(g)At equilibrium, the concentrations of reactants and products are: [CO2] = 0.0400 M, [H2] = 0.0220 M, [CO] = 0.0240 M, and[H2O] = 0.0190 M. This equilibrium is perturbed by adding CO2(g) to the system such that when a new equilibrium isreached, the concentration of CO2 is 0.050 M. What is the concentration of H2(g) at this equilibrium?
