Re: sre

Standard enthalpy of reaction is the enthalpy change that occurs in a system for a reaction in which it’s reactants and products are in their standard state.

Re: sre

You can just think of it as the normal enthaply, except when the conditions of the reactants and products are in the standard state. So it must be in 1 bar and pure states of elements.

Re: sre

The standard reaction enthalpy is just the enthalpy when all reactants and products are in their standard state at 1 atm.

Re: sre

enthalpy of standard state for reactants and products (which are in their standard states)

Re: sre

is standard state at 1 bar or 1 atm
