How do we now that something is at standard reaction enthalpy. I know that it’s enthalpy at pure form but how do we know that? Do they tell us in the question?
I’m also confused on what standard enthalpy of formation is
The reaction enthalpy is the heat released or absorbed for the reaction; it is the difference in enthalpy for the products and reactants. The enthalpy of formation for a mol of substance in its standard state is the change in enthalpy that occurs when that substance is formed from its elements. The enthalpy of formation of products and reactants in a reaction can be used to calculate the reaction enthalpy.
