Solution: The reaction between reactant A (blue spheres) and reactant B (red spheres) is shown in the following diagram:Based on this diagram, which equation best describes the reaction?(a) A2 + B → A2B(b) A2 +

Problem

The reaction between reactant A (blue spheres) and reactant B (red spheres) is shown in the following diagram:
Reactant A is two bonded atoms, while reactant B is a single atom. 4 reactant A plus 4 reactant B go to 4 product molecules, which are all two reactant A spheres bonded to one reactant B sphere.

Based on this diagram, which equation best describes the reaction?

(a) A2 + B → A2B

(b) A2 + 4B → 2AB2

(c) 2A + B4 → 2AB2

(d) A + B2 → AB2
