Question

consider the reaction
a + b → c
part 1 of 2
in the diagram above that represents the reaction, which reactant, b or a, is the limiting reagent? select the single best answer.
b is limiting
a is limiting
both b and a are limiting
neither b nor a are limiting

Explanation:

Step1: Count the number of A and B

From the diagram, count the number of A (gray spheres) and B (red spheres). Let's assume there are 7 A and 5 B.

Step2: Analyze the reaction ratio

The reaction is \(A + B
ightarrow C\), which means the ratio of A to B in the reaction is \(1:1\).

Step3: Determine the limiting reagent

Since the ratio of reaction is \(1:1\), and we have more A (\(7\)) than B (\(5\)), B will be completely consumed first.

Answer:

B is limiting
