How to solve for delta S surroundings at standard conditions

WebEnthalpy, H, is a thermodynamic property that describes the heat lost or gained in a system. The change in enthalpy, ΔH, is equal to the sum of the change in internal energy, ΔU, plus the product of the constant pressure, P, and the change in volume, ΔV. ΔH = ΔU + PΔV. During a chemical reaction, energy is either gained or released. WebI used my chemistry book to find the sum of enthalpy formation per product in combustion such as methane ( -8.90 ) etc. Formula: the enthalpy change for a reaction = sum of the enthalpy of formation of all products - the sum of enthalpy formation of all reactants.
