Combustion of natural gases

  1. May 4, 2008 #1
    I had a question on how to find the stoichimoteric coefficient in combustion reaction contains several types of natural gas.

    Lets say for example: u start with a natural gas (using moral analysis) 0.865CO2 + a0.08C3H8 + b0.02C3H8 c0.035N2 + d(O2 + 3.76) ------> eCO2 + fH20 + gN2;

    Using conseration of mass i get 4 equations + assume that i am start with one mole (0.865 + 0.08a + b0.02 + c0.035 = 1

    that give me 5 equations but i need 7 equations to solve. We are told nothing about the end product, expect that it goes to completion with expess air.

    Could some please help me?
