## Gibbs Free Entropy Solution

STEP 0: Pre-Calculation Summary
Formula Used
Gibbs Free Entropy = Entropy-((Internal Energy+(Pressure*Volume))/Temperature)
Ξ = S-((U+(P*VT))/T)
This formula uses 6 Variables
Variables Used
Gibbs Free Entropy - (Measured in Joule per Kelvin) - The Gibbs free entropy is an entropic thermodynamic potential analogous to the free energy.
Entropy - (Measured in Joule per Kelvin) - Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
Internal Energy - (Measured in Joule) - The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Volume - (Measured in Cubic Meter) - Volume is the amount of space that a substance or object occupies or that is enclosed within a container.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
STEP 1: Convert Input(s) to Base Unit
Entropy: 71 Joule per Kelvin --> 71 Joule per Kelvin No Conversion Required
Internal Energy: 233.36 Joule --> 233.36 Joule No Conversion Required
Pressure: 80 Pascal --> 80 Pascal No Conversion Required
Volume: 63 Liter --> 0.063 Cubic Meter (Check conversion ​here)
Temperature: 298 Kelvin --> 298 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ξ = S-((U+(P*VT))/T) --> 71-((233.36+(80*0.063))/298)
Evaluating ... ...
Ξ = 70.2
STEP 3: Convert Result to Output's Unit
70.2 Joule per Kelvin --> No Conversion Required
FINAL ANSWER
70.2 Joule per Kelvin <-- Gibbs Free Entropy

## What is Debye–Hückel limiting law?

The chemists Peter Debye and Erich Hückel noticed that solutions that contain ionic solutes do not behave ideally even at very low concentrations. So, while the concentration of the solutes is fundamental to the calculation of the dynamics of a solution, they theorized that an extra factor that they termed gamma is necessary to the calculation of the activity coefficients of the solution. Hence they developed the Debye–Hückel equation and Debye–Hückel limiting law. The activity is only proportional to the concentration and is altered by a factor known as the activity coefficient . This factor takes into account the interaction energy of ions in solution.
