Module #13: Thermodynamics Flashcards
1
Q
Change in Enthalpy (Delta H)
A
The energy change that accompanies a chemical reaction.
2
Q
Which (positive or negative) Delta H applies to endothermic and exothermic reactions
A
Delta H is positive for endothermic reactions and negative for exothermic reactions.
3
Q
Hess’ Law
A
Enthalpy is a state of function and is therefore independent of path
4
Q
Enthalpy of formation (DeltaHf)
A
The Delta H of a formation reaction
