Question

why is mole fraction directly proportional to solubility ?​

Answer 1

Answer:

Henry's Law states that:

Pgas=Khx

⇒Kh=Pgasx

Here, xis the mole fraction of the gas dissolved in the solvent, and Pgashappens to be the partial pressure of the gas over the solution.

Now let us assume that the entire system is open, say, we've kept the solution of gas in liquid in an open container, effectively ensuring that Pgasis a constant. Let's vary the temperature. As you can see in the above relation, Khmust vary inversely with mole fraction to keep the partial pressure constant.

Hence, we conclude that the Henry's Law constant varies inversely with mole fraction, which is a measure of solubility. Clearly, the value of Khrises with an increase in temperature, and vice-versa.

Answer 2

Hello buddy....

Here's your answer....

It is briefly explained in "Henry's Law".

According to Henry's law:-

The mole fraction of gas soluble in water is directly proportion to the pressure applied on it. When pressure increases the the soluble increases due to the solvent decrease simultaneously.

Hope this will help yaa buddy....

Say thankx and mark as brainliest if this HELPED you...

Thankyou :)
