CHM 101 Stoichiometry of Chemical Reactions Objective Question

Question

What is one factor that affects the reduction of actual yield compared to theoretical yield?
Options
A Using pure chemicals
B The nature of the reaction - complete conversion is not always possible because a competing reverse reaction takes place
Correct Answer
C Increasing temperature
D Using excess reagents
Correct Answer

Option B is the correct answer.

Detailed Explanation

The complete conversion of reactants to products is not always possible because a competing reverse reaction takes place, as in the ammonia synthesis where ammonia decomposes back to nitrogen and hydrogen.

Hint

The notes list four factors, including this one.
