the ostwald process converts ammonia (NH3) to nitric oxide (NO) by reaction with oxygen in the presence of a catalyst at high temperatures. in a test of the process a reaction vessel is initially charged with 3.90 mol NH3(g) and 4.90 mol O2(g), sealed, and heated at a fixed high temperture. when equilibrium is established the reaction mixtureis analyzed and found to contain 2.90 mol NO(g). what is the quantity of NH3 in the equilnrium reaction mixture? 4NH3(g) + 5O2(g) --> 4NO(g) + 6H2O(g).
