Assignment:
The reaction of ammonia with oxygen (from the air) to form nitrogen monoxide (NO, also known as nitric oxide ) is the first stage in the industrial conversion of ammonia into nitric acid. At the temperatures used, the thermo chemical equation for the reaction is as follows:
4NH3(g) + 5O2 <--->4NO(g) + 6H2O(g) (delta)h=-906Kj
a) Explain the following:
i)The effect that increasing the temperature will have on the rate of the reaction.
ii) The effect that increasing the temperature will have on the rate of the reaction
Your answer to (a)(i) should include a clear statement of Le Chatelier's principle and should show clear understanding of how this principle applies to the situation described.
b) In practice the process for producing NO from ammonia is operated at about 650oC in the presence of a platinum catalyst.
Bearing in mind you answers to part (a), explain the role of the platinum catalyst, nothing how its presence helps to maximize the equilibrium yield of NO whilst also ensuring a reasonable rate of production.
Provide complete and step by step solution for the question and show calculations and use formulas.
