Q of reaction

WebJan 15, 2024 · q = Δ r H ⋅ n where n is the amount that reacts (i.e. the change in the amount of any species divided by its stoichiometric coefficient). What does constant pressure has to do with this equality? Because if we assume such equality of Qp=∆U+P∆V=∆H at constant pressure, then it is also valid at constant volume when ∆V=0 such that Q=∆U=∆H.
