We are asked to determine which relationship is valid for an endothermic reaction.
• Exothermic reactions
▪ lose energy, releases heat, temperature of the surroundings increases
▪ involves bond formation (for phase change: gas → liquid → solid)
▪ ΔH is negative
• Endothermic reactions
For a reaction to be endothermic, which of the following relationships is valid?
a) The energy required to break bonds is greater than the energy involved in bond formation.
b) The energy required to break bonds is less than the energy involved in bond formation.
c) The energy required to break bonds is the same as the energy involved in bond formation.
d) The number of bonds broken equals the number of bonds formed.
