Problem: The reaction between hydrogen and oxygen to form water is highly exothermic. Which statement is true of the energies of the bonds that break and form during the reaction?a) The energy needed to break the required bonds is about the same as the energy released when the new bonds form.b) The energy needed to break the required bonds is less than the energy released when the new bonds form.c) The energy needed to break the required bonds is greater than the energy released when the new bonds form

FREE Expert Solution

We are asked to determine which of the given statements Is true of the energies of the bonds that break and form during the reaction of the formation of water.

Recall that:

Exothermic reactions

lose energy, releases heat, temperature of the surroundings increases
▪ involves bond formation (for phase change: gas → liquid → solid)
ΔH is negative
