question

Consider the reaction 2SO_2(g) + O_2(g) \rightleftarrows 2SO_3(g) : Initially 0.100 moles of SO_2 and 0.100 moles of SO_3 are present in a 2.00 liter flask at a temperature of 27°C. Equilibrium is attained at a pressure of 2.78 atm. Calculate a) the mole fraction of O_2 at equilibrium; b)K_p; c) the percent dissociation of SO_3 if 0.100 mole of SO_3 and no (zero) O_2 and no (zero) SO_2 were present initially in the flask.
