Problem: Consider the reaction:4 HCl(g) + O2(g) → 2 H2O(g) + 2 Cl2(g)Each molecular diagrams represents an initial mixture of the reactants.Which mixture produces the greatest amount of products?

FREE Expert Solution

a.

7 mol HCl×2 mol H2O4 mol H2O = 3.5 mol H2O

1 mol O2 ×1 mol O22 mol H2O = 0.5 mol H2O → limiting


b.

5 mol HCl×2 mol H2O4 mol H2O = 2.5 mol H2O

3 mol O2 ×1 mol O22 mol H2O = 1.5 mol H2O → limiting

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.

Which mixture produces the greatest amount of products?
