is defined as the enthalpy change associated with an isolated gaseous atom (x) when it gains an electron to form its corresponding anion. the reaction can be given as below: \(\begin{array}{l}x (g) + e^{-} \rightarrow x^{-} (g)\end{array} \) on the basis of the nature...

is a state function. units used to express enthalpy are calorie, btu, or joules. it is not possible to measure the total enthalpy of the system directly due to which, change in enthalpy is generally measured during experiments. table of contents enthalpy equation what is the enthalpy change?
Enthalpyis the total potential energy of a system. In many cases, the only work “w” done on a system results in a change in the calorific value of the available mass. In other words: (2.3)Energy=Δmc2, Therefore, the heat absorbed (q) in a process, measured under conditions of con...
The entropy change, ΔS, as a result of adsorption, is dominated by the loss of the degrees of freedom of the H2 in the transition from its gaseous to adsorbed state. Although the exact value of ΔS is dependent, to a certain extent, on the level of confinement of the adsorbate in ...
Note that this operation does not change the value of H, because it is equivalent whether you have it written like this or if you subtract similar variables (a la algebra). In the end you obtain your final equation (the one you were looking for)...
