State properties

Postby Valeria Viera 1B » Fri Jan 25, 2019 9:07 pm

In Wednesday’s lecture professor Lavelle said enthalpy has state properties but heat does not
Can anyone explain to me

Thank you!

Heat does not have state properties because it is not a state function meaning that heat relies on the ‘path taken’ where as enthalpy does not and its value is determined by its current state

Adding on to that, because enthalpy is a state function, you can calculate it by adding the enthalpies of multiple reactions to find the enthalpy of the overall reaction.

Enthalpy of a reaction with multiple steps can be found by adding the enthalpy of each step together because it is a state function, while the same can not be done with heat.
