Introduction to Enthalpy of Reaction
- Enthalpy (H) = heat
- Is an extensive property and state function
; 
- E is the internal energy of the system, P is the pressure of the system, and V is the volume of the system
- Units of ΔH = kJ
- When a reaction and ΔH are given, changing the coefficients/amounts changes ΔH by the same factor
- Heat value written on reactant side = endothermic
- Heat value written on product side = exothermic & ΔH will be negative
