Ammonia is commonly made form N2 and H2 bythe Haber process. Because the reaction reaches equilibrium before going completely to product, the stoichiometric amount of ammoniais not obtained. At a particular temperature and pressure, 10.0 gof H2 reacts with 20.0 g of N2 to form ammonia. When equilibrium is reached, 15.0 g of NH3 has formed.
(a) Calculate the percent yield.
(b) How many moles ofN2 and H2 are present at equilibrium?
