Re: Hess Law [ENDORSED]
Remember in class I discussed enthalpy is a state function. Therefore reversing the reaction must result in a change in sign for the enthalpy.

Re: Hess Law
You would just flip the sign, since the energy would be going (inflow or outflow) the opposite way.

Re: Hess Law
You would change the sign in that case because it is now the reverse of the reaction, therefore the enthalpy of the equation is now reversed you essentially multiply by -1
