a) Determine the value for the equilibrium constant if there are present at equilibrium 5.0mol of Nitrogen, 7.0 mol Oxygen, and 0.10 mol NO2 in a 1.5 L vessel.

N2 + O2 --> 2NO2

b) Determine the value for the equilibrium constant for the reaction A+ B --> 2C, if 1.0 mol A, 1.4 mol B, and 0.50 mol C are places in a 1.0 L vessel and allowed to come to equilibrium. The final concentration of C is 0.75M.
