How is enthalpy a state function
WebA) Internal energy is a default function. - True, inhouse energy depends only upon the current state of one system, not on this track taken to outreach that state. B) The calorimetry change for one reaction is equal in magnitude, but opposite in sign, to the enthalpy change with the invert reaction. - True, this is a consequence of Hess's law.

WebImportantly, entropy is a state function, like temperature or pressure, as opposed to a path function, like heat or work. This means that as a system changes in entropy, ...
WebIn the case of water, the enthalpy is a function of temperature and pressure. To determine the enthalpy of water at 220 °C and 0.01 MPa, we need to use interpolation, which is a mathematical method of estimating values within a range of known data points. In this case, we will use the steam tables, which are tables that provide thermodynamic ... Web7 apr. 2024 · ΔG = ΔH – TΔS = 40630 - 300 x 108.8 = 7990J mol-1.
