For reactions involving solids and liquids, ΔV is usually very small because solids and liquids do not expand or contract significantly as pressure changes. For such reactions neglecting PΔV, ΔH = ΔU. songs written by phil cross

Webb8 okt. 2024 · There are a few steps in calculating Qp in Chemistry. They are as follows: 1) Firstly, calculate the change in enthalpy (ΔH) This can be done by using the equation ΔH = qp + w. 2) Next, calculate the change in entropy (ΔS) This can be done by using the equation ΔS = -q/T. 3) Finally, calculate Qp by using the equation Qp = ΔH – TΔS. Webb26 jan. 2024 · This can also be proven with equations. Because ΔH = ΔU + PΔV and ΔU = q + w, you can plug ΔU into the ΔH equation as follows: ΔH = q + w + PΔV. Because w = …
