In a Self-Contained Breathing Apparatus, Potassium Superoxide, KO₂, Reacts with Carbon

Multiple Choice

In a self-contained breathing apparatus, potassium superoxide, KO₂, reacts with carbon dioxide to form potassium carbonate and oxygen. Identify the limiting reactant and determine the amount of oxygen gas, in moles, that can be produced from 250 g of KO₂ and 450 g of CO₂.
4KO₂(s) + 2CO₂(g) $\rightarrow$ 2K₂CO₃(s) + 3O₂(g)

A) potassium superoxide limiting, 4.75 mol
B) potassium superoxide limiting, 1.53 mol
C) potassium superoxide limiting, 2.64 mol
D) carbon dioxide limiting, 1.53 mol
E) carbon dioxide limiting, 2.64 mol
