General Education Common Graded Assignment:CHEM 107 Fall 2020
The Haber Process
Fundamentals of Chemistry (CHEM 107)is a general education course designed to assist students in the development of critical life skills. One of the goals of this assignment is to assess student competence for each of these objectives:
In addition to the above general education objectives, this assignment assessesstudents’ understanding and application of the following skills and knowledge specific to Thermochemistry:
Students are asked to calculate the theoretical yield of a reaction where one reagent, whose amount determines how much product will be formed, is completely consumed. The other reagent is used in excess amount and is, therefore, not a limiting factor to the amount of product that will be formed.
Using the internet and/or any library database as one of the learning tools, independent learning, critical thinking, and effective written communication skills will be required in order for students to express their opinion on the controversy surrounding the award of the Nobel Prize to the chemist who invented the process.
By tying the concepts of percent yield and theoretical yield together, students can calculate the amount of reagent needed to yield a specified amount of product given a percent yield, demonstrating critical thinking skills.
This project highlights a process called the Haber process that has a significant contribution to modern society with an interesting background story that would promote cultural appreciation.
Audience:Other CHEM 107 students
See attached instructions for detaileddirections for completing this activity. Students should complete the assignment and turn in a completed Answer Sheet and Essay.
While the majority component of air is nitrogen (N2), the gas is very unreactive because of its stability due to the triple bonds that hold the nitrogen atoms together. Nitrogen gas is, therefore, relatively unavailable for chemical reactions. One of the few ways to “fix” nitrogen, making a nitrogen compound from the elemental nitrogen in the atmosphere, is the Haber process (aka Haber-Bosch process). In this reaction, nitrogen gas combines with hydrogen gas to yield ammonia. The enthalpy (ΔH) of this reaction is 92.22 kJ.
This process was discovered by the German chemist Fritz Haber in the early twentieth century. Through extensive experimentation, Haber found the conditions that would produce adequate yields (at a temperature of about 500 oC and a pressure of about 200 atm). This process holds a significant importance today because of its application in the industrial production of ammonia-based fertilizer. In 1918, Haber received the Nobel Prize in Chemistry for his work. However, a lot of controversy followed the Nobel Prize award.
For this experiment, 16.55 grams of nitrogen gas and 10.15 grams of hydrogen gas are allowed to react in the reaction vessel. The ammonia vapor that is produced is then condensed, liquefied, and collected into a collection vessel.
Students must work individually. The following questions refer to the reaction described above.
