Enthalpy calculation
Web1. standard enthalpy (with the little circle) is the enthalpy, but always under one atmosphere of pressure and 25 degrees C. 2. I believe both equations can work for both … WebHess's law states that the total enthalpy change does not rely on the path taken from beginning to end. So, you can calculate the enthalpy as the sum of several small steps. There are a few rules that you must follow when manipulating an equation. You can reverse the equation. This will change the sign of #ΔH#.
