1
Q
Hess’s Law
A
The enthalpy change accompanying a chemical reaction is independent of the pathway between the initial and final states
2
Q
Standard enthalpy change of formation
A
The enthalpy change when one mole of a substance is formed from its elements in their standard states under standard conditions
3
Q
Standard state
A
The pure substance at 100kPa and a specified temperature
4
Q

A
Zero
5
Q
Relationship between enthalpy change of reaction and enthalpy change of formation
