WebNov 2, 2024 · As enthalpy is a state function, change in enthalpy (ΔH) will depend on the initial and the final states of the system. ΔH = H 2 – H 1. Here, H 1 is the enthalpy of the system in the initial state and H 2 is the enthalpy of the system in the final state. So if we write the enthalpy’s formula ( H = U + PV ) in a similar form.

Webe. In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes. Given a discrete random variable , which takes values in the alphabet and is distributed according to : where denotes the sum over the variable's possible values. WebEnthalpy. Enthalpy (ΔH) refers to the total heat content of the system, if the change in enthalpy is positive, the reaction is endothermic in nature, and a lower enthalpy means it requires less energy. ... This result does not mean that the absolute value of enthalpy at 25°C is 0.91 kJ; we can say only that the enthalpy at 25°C is 0.91 kJ ... the most famous buddhist cave temple
