Question

consider the following equilibrium at 686 deg c
CO2(g) + H2(g) <------> co(g) + H20(g)

the equilibrium concentrations of the reactant species are
[co] = 0.050M, [h2]= 0.045M [co2]=0.096M [h2o]=0.040M
a) calculate kc for the reaction at 686 deg c
b) if the equilibrium concentration of co2 were raised to 0.50M andkc value was determined to be 0.52, what would be the equilibriumconcentrations of all the gases?
