Only One Option Correct Type
This section contains 11 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONLY ONE is correct
An unopened soda has an aqueous concentration of C02 at 25 °C equal to 0.0506 molal. Thus, pressure of C0₂ gas in the can is (K_H = 0.034 mol/kg bar) 

CO(g)is dissolved in H₂ Oat 25 °C and 0.010 atm. Henry ’s law constant for this system is 5.80 x10⁴ atm. Thus, mole fraction of CO(g)is

 H₂ S gas is used in qualitative analysis of inorganic cations. Its solubility in water at STP is 0.195 mol kg^-1 . Thus, Henry ’s law constant (in atm molar^-1 ) for H₂ S is

 Variation of K_h (Henry ’s law constant) with temperature T is shown by following graphs I - IV.

Correct representation is

Concentration of C0₂ (in mole fraction) in fat when partial pressure of C0₂ is 55 kPa at 25 °C, is (Henry ’s law constant of C0₂ = 8.6 x 10⁴ torr)

What is the concentration of 0₂ in a fresh water stream in equilibrium with air at 25 °C and 1.0 bar? Given, K_H (Henry ’s law constant) of 0₂ = 1.3 x 10^-3 mol/kg bar at 25 °C.

Following data has been given for C0₂ for the concentration in H₂ 0.

If solution of C0₂ in H₂ 0 is heated from 273 to 333 K, pressure ( p₂ ) needed to keep C0₂ in the solution is

Relation between the volume of gas (2) that dissolves in a fixed volume of solvent(1) and the partial pressure of gas (2) is (n_t = total moles, K₁ and K₂ are Henry ’s constants)

Which is correct about Henry 's law

Henry ’s law constant for N₂ at 293 K is 76.48 kbar. N₂ exerts a partial pressure of 0.987 bar. If N₂ gas is bubbled through water at 293 K, then number of millimoles of N₂ that will dissolve in 1 L of water is

A handbook lists the solubility of carbon monoxide in water at 0 °C and 1 atm pressure as 0.0354 mL CO per mL of H₂ 0. What should be the pressure of CO(g) above the solution to obtain 0.010 M CO solution?
