The value of Henry s law constant increases with increasing temperature?
The Henry s law constant for O<sub>2</sub> in water at 25 C is 1.27 10<sup> 3</sup>M/atm and the mole fraction of O<sub>2</sub> in the atmosphere is 0.21. Calculate the solubility of O<sub>2</sub> in water at 25 C at an atmospheric pressure of 1.00 atm.<br>Strategy: Use Dalton s law of partial pressures to calculate the partial pressure of oxygen.
Henry Law s Constants at a system temperature of 25 C (77 F) of nitrogen is 1600 atm/(mol/litre). Molar weight of N<sub>2</sub> is 28.0134 g/mol and partial fraction in air is ~ 0.79. Calculate the Nitrogen dissolved in the Water at atmospheric pressure.
