HCl is oxidized by O2 to produce water and Cl2. We have three different mixtures of reactants and we have to determine which mixture produces the greatest amount of Cl2 gas.


We need to find the mixture that produces the greatest amount of products first.



In each diagram the spheres represent:

  • white + green → HCl
  • 2 red → O2

From the balanced reaction:

  • 4 molecules of HCl will react with 1 molecule of O2.
  • This is required to run the reaction once (4 HCl :1 O2).

Problem Details
Consider the reaction:

4 HCl(g) + O2(g) → 2 H2O(g) + 2 Cl2(g)

Each molecular diagrams represents an initial mixture of the reactants.

Three space-filling molecular diagrams labeled a, b, and c. Diagram a is a collection of seven molecules composed of a green and smaller white sphere combined, and one molecule composed of two red spheres combined. Diagram b is a collection of six molecules composed of a green and smaller white sphere combined, and three molecules composed of two red spheres combined. Diagram c is a collection of four molecules composed of a green and smaller white sphere combined, and five molecules composed of two red spheres combined.

How many molecules of Cl2 would be formed from the reaction mixture that produces the greatest amount of products?
