The result of a dry gas analysis of an engine exhaust is co2 = 10.7%, co=5.8%, and n2=83.5%. stating any assumptions, use the rich gas equation to find the gravimetric air/fuel ratio.

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
