Question

In a reaction $A + B_2 \rightarrow AB_2$, identify the limiting reagent if 300 atoms of A and 200 molecules of $B_2$ react:

Prashant Kotian · Accepted Answer

Correct answer: B. Stoichiometry is .
To react 300 atoms of A, 300 molecules of are needed.
We only have 200 molecules of , so is limiting. [17, 18]
