Chapter 6: Challenge Problem/OWL 100. Suppose 1.50 atm of CH4(g), 2.50 atm of C2H6(g), and 15.00 atm of O2(g) are placed in a flask at a given temperature. The reactions are: CH4(g) + 2O2(g) CO2(g) + 2H2O(g) Kp = 1.0 x 104 2C2H6(g) + 7O2(g) 4CO2(g) + 6H2O(g) Kp = 1.0 x 108 Calculate the equilibrium pressures of all gases.
