Equilbrium Question
« on: November 22, 2007, 08:17:53 PM »
Suppose 1.02 atm of CH4(g), 2.63 atm of C2H6(g), and 14.94 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.
PCH4
  ______atm
PC2H6
  ______atm

For a such big Kp and an excess of O2 forget about equlibrium, do simple stoichiometry.
I think your error will be much less than 1%.
