Myka Glover Task 1 Analyzing the Problem In any engineering design problem, the first step is to understand the problem and identify one or more possible solutions. In this task, you’ll analyze the problems you face as the chemical engineer challenged with setting up the ammonia-making process. Recall the chemical equation for producing ammonia: N2 + 3H2 2NH3 + energy Part A Explain the problem surrounding the ammonia-making process in terms of chemical equilibrium.
Part B How can you change the chemical equilibrium to benefit the company? What benefits will be realized?
Part C Design criteria are the desired features of a design. Identify at least two criteria for the design of the ammonia-making process. Explain why these criteria are important. Answer:
Part D Le Chatelier’s principle describes how chemical equilibriums respond to changes in the concentrations of reactants or products. Think about how you can use Le Chatelier’s principle to nd possible solutions to the design problem. Describe at least two ways to increase the yield (amount) of ammonia-based on this principle.
Task 2 Simulating Possible Solutions In this task, you’ll use a simulation to test a model for synthesizing ammonia. Recall the chemical equation for the reaction: N2 + 3H2 2NH3 + energy To begin, open the simulation and click the Rate experiments tab. Locate the Initial condition window in the top-right corner of the screen. In the Select, a reaction drop-down menu, choose Design your own. Part A Look at the window on the left side of the simulation. It shows the reaction A + BC AB + C. How does this reaction differ from the reaction by which ammonia is synthesized?
