Assertion (A) For dissolution of gases in liquids, on increasing the temperature or decreasing the pressure the amount of gas dissolved decreases. Reason (R) For dissolution of gases in liquids, the concentration of a gas in liquid is inversely proportional to the pressure (concentration) of the gas over the liquid.

Question

Assertion (A) For dissolution of gases in liquids, on increasing the temperature or decreasing the pressure the amount of gas dissolved decreases. Reason (R) For dissolution of gases in liquids, the concentration of a gas in liquid is inversely proportional to the pressure (concentration) of the gas over the liquid. (A) Both A and R are correct; R is the correct explanation of A (B) Both A and R are correct; R is not the correct explanation of A (C) A is correct; R is incorrect (D) A is incorrect; R is correct

Tardigrade Admin · Accepted Answer

Dissolution of gases in liquid is that the concentration of a gas in liquid is proportional to the pressure (concentration) of the gas over the liquid. Thus, A is correct but R is incorrect.

Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$

Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$

$A$ is correct; $R$ is incorrect

$A$ is incorrect; $R$ is correct

Dissolution of gases in liquid is that the concentration of a gas in liquid is proportional to the pressure (concentration) of the gas over the liquid.
Thus, $A$ is correct but $R$ is incorrect.
