The equilibrium constant, K, for the following reaction is 6.30 at 723K. 2NH3(g) N2(g) + 3H2(g) If an equilibrium mixture of the three gases in a 10.1 L container at 723K contains 0.410 mol of NH3(g) and 0.250 mol of N2, the equilibrium concentration of Hy is M.
1. The reaction N2 + 3 H2 2NH3 is used to produce ammonia. When 450. g of hydrogen is reacted with nitrogen, 2550 g of ammonia should be produced. If a chemist actually obtains 1,977 g of ammonia in the lab, what is the percent yield of this reaction? Report your answer to the correct degree of certainty. Do not included units (% yield is understood). 2.Calculate the volume of 2.12 moles of nitrogen gas at temperature of 31.7 oC and a pressure of...
