which process would produce a similar pathway?\ncondensation\ndehydration\ndecomposition\nmelting

Brief Explanations:

The graph shows an exothermic reaction where reactants (A + B) have higher energy than the product (C). Condensation is an exothermic process where a gas changes to a liquid, releasing energy. Dehydration is endothermic (removing water often requires energy), decomposition can be endothermic or exothermic but not typically as straightforwardly exothermic as condensation in this context, and melting is endothermic (requires energy to change a solid to a liquid).

Answer:

condensation
