Using the single-step global mechanism for combustion of a hydrocarbon with air,

compare the mass rates of fuel carbon conversion to CO, for 0 =1, P= 1 atm, and T = 1600 K for the following fuels: A. CH4 - methane B. C;Hg- propane C. C3H18 octane Single-step global mechanism: C,H, +(x+ y/4)0,XCO, + (y/2)H,0 d[C,H,] - E, :-Aexp CH,"[0,r" dt RT [=]gmol/cm - Hint: Make sure that you include the nitrogen from the air in determining your reactants' concentrations.
