I believe c is the right answer.
Answer:
P (H₂) = 741 torr
Explanation:
Let's begin by listing out the given parameters:
Temperature (water) = 298 K, volume = 45.6 mL,
atmospheric pressure, P (total) = 765 torr, vapor pressure of water, P (H₂O) = 24 torr
To get the pressure of inside the tube, P (H₂), we apply Dalton's Law of Partial Pressure and we have:
P (total) = P (H₂) + P (H₂O)
P (total) = 765 torr, P (H₂O) = 24 torr
P (H₂) = P (total) - P (H₂O) = 765 - 24
P (H₂) = 741 torr
It therefore becomes clear that the pressure of H₂(g) is 741 torr
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 = 
where, S = entropy
= Boltzmann constant
= 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
= 1, and
= 0.833
Therefore, change in entropy will be calculated as follows.

= 
= 
= 
or, = 
Thus, we can conclude that the entropy change for a particle in the given system is
J/K particle.
Answer:
The answer is the same as .
