A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the f

deff fn [24]

Explanation:

Entropy means the amount of randomness present within the molecules of the body of a substance.

Relation between entropy and microstate is as follows.

S = $K_{b} \times ln \Omega$

where, S = entropy

$K_{b}$ = Boltzmann constant

$\Omega$ = number of microstates

This equation only holds good when the system is neither losing or gaining energy. And, in the given situation we assume that the system is neither gaining or losing energy.

Also, let us assume that $\Omega$ = 1, and $\Omega'$ = 0.833

Therefore, change in entropy will be calculated as follows.

$\Delta S = K_{b} \times ln \Omega' - K_{b} \times ln \Omega$

= $1.38 \times 10^{-23} \times ln(0.833) - 1.38 \times 10^{-23} \times \times ln(1)$

= $1.38 \times 10^{-23} \times (-0.182)$

= $-0.251 \times 10^{-23}$

or, = $-2.51 \times 10^{-24}$

Thus, we can conclude that the entropy change for a particle in the given system is $-2.51 \times 10^{-24}$ J/K particle.

EASY 100 POINTS, WILL MARK BRAINLEST, 2 QUESTIONS, SHOW YOUR WORK OR NO POINTS

SVETLANKA909090 [29]

Answer:

Explanation:

1. Please provide the enthalpy info - I will work on it with the info

i) Reaction a should be modified to match the number of S in equation:

2S + 2O2 -> 2SO2 deltaH = -370kJ

ii) Reaction b should be written reversely to match the reactants of SO2:

2SO2 + O2 -> 2SO3 deltaH = 256kJ

iii) Adding the equations together:

2S + 3O2 -> 2SO3

iv) Enthalpy of the combined reaction = -370+256 = -114kJ

It is negative so the reaction is exothermic.
