IV. At 800K,2.00 moles of NO are mixed with 1.00 mole of O2. The reaction 2NO(g)+O2(g)=2NO2(g) comes to equilibrium at a total pressure of 1 bar. Analysis of the system shows that 0.71 moles of oxygen are present at equilibrium. a) Calculate the equilibrium constant for the reaction. (15 points) b) Calculate G for the reaction at 800K.
