A) Partial pressure of a gas is related to number of moles of the dissolved gas and \[{{K}_{H}}\] (Henry's constant)
B) \[{{O}_{2}}(g)\] and \[{{N}_{2}}(g)\] are less soluble in \[{{H}_{2}}O\] and solubility of these gases decrease with increase of temperature. These gases have higher \[{{K}_{H}}\] value at a given pressure and \[{{K}_{H}}\] value increases with temperature.
C) \[S{{O}_{2}}(g)\]and \[N{{H}_{3}}(g)\] are more soluble in \[{{H}_{2}}O\] and solubility of these gases decrease with increase of temperature These gases have lower \[{{K}_{H}}\] value at a given pressure.
D) Helium \[(g)\] and Argon \[(g)\]are sparingly soluble in acetone and solubility of these gases increases increase slightly with increase of temperature. These gases have higher \[{{K}_{H}}\]value at a given pressure.
Correct Answer: A
Solution :
[a] CORRECT statement (I): Partial pressure of a gas is related to mole fraction of the dissolved gas and \[{{K}_{H}}\] \[\therefore \,\,\,P={{x}_{2}}{{K}_{H}}\].
