- Reference states for enthalpies need to be clearly specified in an energy balance.
- An energy balance for a reactor can contain a heat of reaction term explicitly or heats of formation can be incorporated into individual enthalpies.
- An inert, even though not involved in a reaction, can affect the outlet temperature or the amount of heat added or removed.
