A 1.00L flask was filled with 2.00 moles of gaseous SO2 and 2.00 moles of gaseous NO2 and heated. After equilibrium was reached, it was found that 1.30 moles of gaseous NO was present. Assume that the reaction

SO2(g) + NO2(g) <--> SO3(g) + NO(g)

occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.

When 1.50 mol CO2 and 1.50 mol H2 are placed in a 3.00 L container at 395°C, the following reaction occurs:

CO2(g) + H2(g) <--> CO(g) + H2O2(g)

If Kc = 0.802, what are the concentrations of each substance in the equilibrium mixture?
