An increase in the temperature of a solution usually: a)increases the boiling point. b)increases the solubility of a gas in the
1 answer:
Answer: Option (c) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
Since, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then this will also lead to increase in kinetic energy of the molecules of a substance.
So, when a solid substance is dissolved in a solution whose temperature is increased then molecules of the solid will also gain kinetic energy. As a result, more number of collisions will occur due to which bond between the molecules of solid will break.
Therefore, there will be increase in solubility of the solid.
Thus, we can conclude that an increase in the temperature of a solution usually increases the solubility of a solid solute in the solution.

At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
<h3>What is Henry's Law ?</h3>Henry's Law is a gas law states that at a constant temperature the amount of gas that dissolved in a liquid is directly proportional to the partial pressure of that gas.
<h3>What is relationship between Henry's Law constant and Solubility ?</h3>The solubility of gas is directly proportional to partial pressure.
It is expressed as:
where,
= Solubility of gas
= Henry's Law constant
= Partial pressure of gas
Now put the values in above expression we get
0.080M = × 1.7 atm
= 0.047 M/atm
Now we have to find the partial pressure of He
0.200 M = 0.047 M/atm ×
= 4.25 atm
Thus from the above conclusion we can say that At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
