What to Focus On
- System: part under study; Surroundings: rest of the universe
- Isolated system: no exchange of matter or energy
- Closed system: exchanges energy but not matter
- Exothermic: heat is released (ΔH < 0)
- Endothermic: heat is absorbed (ΔH > 0)
- Exothermic feels hot; endothermic feels cold
- ΔH includes sign: negative for exothermic, positive for endothermic
- States of matter must be specified
- ΔH is proportional to moles involved
Common Mistakes to Avoid
ΔH and ΔU are always the same for all reactions.
Exothermic means the reaction is fast, and endothermic means it's slow.
ΔH is the heat content of a substance.
