Explanation:
(a) The given data is as follows.
Temperature (T) = = (25 + 273) K = 298 K
= 43000 J/mol
Since, both the liquid and vapors are at equilibrium. Therefore, change in free energy will be calculated as follows.
= 0
43000 - = 0
= -144 J/mol K
Negative sign indicates an increase in entropy of the system.
Now, for 1 mole of is as follows.
= 144 J/K
So, - 214 = 144 J/k
= 358 J/K
Therefore, we can conclude that entropy of vapor is 358 J/K.
(b) As we know that intensive variable are the variables which do not depend on the amount of a substance.
So, in the given situation only temperature will act as an intensive variable that will be required to completely specify the vapor-liquid mixture of .
Answer:
The balanced reaction in the acidic medium is:
Explanation:
1) ( oxidation)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions on the side where hydrogen are less.
Add electrons to balance charge where positive charge is more.
..[1]
2) (reduction)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions by adding them on the side where hydrogen are less.
..[2]
Add electrons to balance charge where positive charge is more.
..[2]
3 × [1] + 2 × [2]
The balanced reaction in the acidic medium is:
