Delta H and q

Postby Shirley Liu 2I » Sun Feb 03, 2019 9:54 pm

How are delta H and q related? Are they the same thing and can be used interchangeably? In what contexts do you use each one?

I'm pretty sure q and delta H are the same thing.

delta h is the change in enthalpy of the system and q is the heat given off or absorbed in the system
