For this you will need the latent heat capacity for the vaporization of water.
Explanation:
Sublimation is defined as a process in which solid state of a substance directly changes into vapor or gaseous state without undergoing liquid phase.
For example, naphthalene balls show sublimation at room temperature.
As this process does not cause any change in chemical composition of a substance. Hence, it is known as a physical process.
Similarly, when sublimes readily at . This shows change in physical state of carbon dioxide is taking place, i.e, from solid to gaseous phase.
Thus, we can conclude that when sublimes readily at then it means physical properties are usually associated with a compound that undergoes this kind of change.
Explanation:
The given data is as follows.
= 286 kJ =
= 286000 J
,
Hence, formula to calculate entropy change of the reaction is as follows.
=
=
= 163.5 J/K
Therefore, formula to calculate electric work energy required is as follows.
=
= 237.277 kJ
Thus, we can conclude that the electrical work required for given situation is 237.277 kJ.
<u>Answer:</u> The pressure of carbon dioxide needed is 2.94 atm
<u>Explanation:</u>
To calculate the partial pressure of carbon dioxide, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= molar solubility of carbon dioxide gas =
= pressure of carbon dioxide = ?
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide needed is 2.94 atm
