An initial mixture of nitrogen gas and hydrogen gas are allowed to react in order to reach equilibrium by the following reaction:
3 H2(g) + N2(g) ? 2 NH3(g)
At equilibrium, [H2] = 5.0 M, [N2] = 8.0 M and [NH3] = 4.0 M. What was the initial concentration of H2(g) before any reaction occurred?
What is the percent yield of a reaction in which 222 g phosphorus trichloride reacts with excess water to form 141 g HCl and aqueous phosphorus acid (H3PO3)?
Provide a method for seperating the mixtures of the compounds, dissolved in a solvent diethyl ether. In each case one of the components will be neutral compound. Give your answer in the form of flow chart.
