question 10

Multiple Choice

In the reaction
2A + 3B → C
4) 0 mol A react with 4.0 mol B. Which reactant is limiting?

• A) A is limiting because there are 2 mol of it but 4.0 mol are needed.
• B) B is limiting because there are 4.0 mol of it but 6.0 mol are needed.
• C) A is limiting because 2 is smaller than 3 (the coefficients in the balanced equation).
• D) Neither is limiting because equal amounts (4.0 mol) of each reactant are used.
• E) B is limiting because 3 is larger than 2 (the coefficients in the balanced equation).
