Enthalpy (H) is the transfer of energy in a reaction (for chemical reactions it is in the form of heat) and ΔH is the change in enthalpy. ΔH is a state function. Being a state function means that ΔH is independent of the processes between initial and final states. In other words, it does not matter what steps we take to get from initial reactants to final products—the ΔH will always be the same. ΔHrxn, or the change in enthalpy of a reaction, has the same value of ΔH as in a thermochemica… WebApr 17, 2024 · One-dimensional (1D) vanadium oxide nanobelts (VOx NBs) with variable V valence, which include V3O7·H2O NBs, VO2 (B) NBs and V2O5 NBs, were prepared by a simple hydrothermal treatment under a controllable reductive environment and a following calcination process.
