Examine the energy diagram. Which equation would represent this reaction and energy change?

Question

AB + energy --> A⁺ + B⁻

AB --> A⁺ + B⁻ + energy

A⁺ + B⁻ + energy --> AB

A⁺ + B⁻ --> AB + energy

Answer 1

The correct equation that represents this reaction and energy change is: AB --> A⁺ + B⁻ + energy. This is because the energy is being added to the reactant (AB) to break the bond and form the products (A⁺ and B⁻) with the release of energy.
