Ammonia is manufactured in an exothermic reaction between nitrogen and hydrogen in the presence of an iron catalyst: The nitrogen and hydrogen mixture is passed into a reaction chamber at a pressure of 200 atmospheres and a temperature of 4500C. The reaction is reversible. (a) Why is a catalyst needed? The mixture of gases leaving the reaction chamber still contains some unreacted nitrogen and hydrogen- and Explain how the ammonia can be separated from this unreacted nitrogen and hydrogen. (c)...
What is the balanced equation that represents the reaction between hydrogen and nitrogen to make ammonia (NH3)? How many molecules of ammonia can be created when four molecules of nitrogen are combined with four molecules of hydrogen? Include a drawing of the molecules in your answer. What ratio of nitrogen and hydrogen molecules would result in no left-over reactants? Explain your answer. If 100.0g of nitrogen is reacted with 100.0g of hydrogen, what is the excess reactant? What is the...
