Question

An engineer thinks that changing the catalyst used in a chemical reaction will
increase the rate of the reaction. This is an example of which step in the
engineering process?
A. Manufacture and test a prototype.
B. Identify solutions to the problem.
C. Plan a detailed design.
D. Research the problem.

Answer 1

Answer:

B. Identify solutions to the problem.

Explanation:

In the case described above, the engineer has already designed and attempted to manufacture a prototype for the process. The design of the process must have also been carefully researched and planed.

However, he identified the problem of low yield and is now working towards identifying solutions to the problem. One option he seeks to explore according to the question is to change the catalyst used in the reaction.
