Ludwig Boltzmann developed a model that relates entropy to _________.

Chemistry
1 answer:
kifflom [539]3 years ago
5 0

Answer:

the number of possible configurations of the locations and energies of the atoms or molecules that comprise a system

Explanation:

Ludwig Boltzmann was the first to suggest that the concept of entropy could be calculated by examining the positions and energies of molecules. This was developed into an equation, known as the Boltzmann equation, which relates entropy to the number of microstates (W):

S = k ln W

where k is the Boltzmann constant (1.38 x 10-23 J/K), and W is the number of microstates.

Microstates was used to imply the number of different possible arrangements of molecular position and kinetic energy at a particular thermodynamic state. Therefore any process that gives an increase in the number of microstates therefore increases the entropy. Hence the answer.

At a particular temperature, 12.0 moles of so3 is placed into a 3.0-l rigid container, and the so3 dissociates by the reaction 2
saul85 [17]
            2 SO₃ --> 2 SO₂ + O₂
I             12             0          0
C           -2x           +2x      +x
---------------------------------------------
E         12-2x          2x         x

Since the moles of SO₂ at equilibrium is 3 mol, 2x = 3. Then, x = 1.5 mol. So, the amounts at equilibrium is:
SO₃: 12 - 2(1.5) = 9
SO₂: 2(1.5) = 3
O₂: 1.5

The formula for K basing on the stoichiometric reaction is:
K = [SO₂]²[O₂]/[SO₃]² 
where the unit used is conc in mol/L.

K = [3 mol/3 L]²[1.5 mol/3 L]/[9 mol/3 L]²
<em>K = 0.0556</em>

Calculate the molality and van’t Hoff factor (i) for the following aqueous solutions:
MissTica

The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.

<h3>What is the value of Van t Hoff factor?</h3>

For most non-electrolytes dissolved in water, the Van 't Hoff factor is essentially $ 1 $ . For most ionic compounds dissolved in water, the Van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance.

<h3>Which has highest Van t Hoff factor?</h3>

The Van't Hoff factor will be highest for

   A. Sodium chloride.

   B. Magnesium chloride.

   C. Sodium phosphate.

   D. Urea.
