2.1 Thermo Flashcards
1
Q
Hess’s Law
A
Hess’s Law states that, if a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route.
2
Q
Enthalpy Change
A
The heat energy exchanged with the surroundings at a constant pressure.
3
Q
Standard Molar Enthalpy Change
A
The enthalpy change when mole of a compound is formed from its elements in their standard states.
4
Q
Bond Enthalpy
A
The enthalpy change required to break and separate one mole of bonds in the molecules of a gaseous element or compound. The resulting gaseous species exert no forces on each other.
