General Chemistry -- Chemical Equilibria Suppose 1.22 atm of CH4(g), 2.57 atm of C2H6(g), and 15.00 atm of O2(g) are placed in a flask at a given temperature. The reactions are given below. CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g) KP = 1.0x10^4 2 C2H6(g) + 7 O2(g) 4 CO2(g) + 6 H2O(g) KP = 1.0x10^8 Calculate the equilibrium pressures of all gases. --- There seems to one unknown that cannot be solved for! Any help is appreciated! (I'd rather not have you post the answer, but rather the method) Thanks.
