We’re being asked to classify vaporization as exothermic or endothermic.
• Exothermic reactions: lose energy and involve bonds forming; ΔH is negative
• Endothermic reactions: gain energy and involve bonds breaking; ΔH is positive
Consider the vaporization of liquid water to steam at a pressure of 1 atm.
Is this process endothermic or exothermic?
