Document Summary
Expressing vapor pressure data: vapor pressure data plotted as lnp versus 1/t ln p = -a ( ) + b. Clausius-clapeyron equation for pvap: another useful equation correlating pvap to temperature is the. William henry found that the solubility of a gas increases with increasing pressure. William henry found that the solubility of a gas increases with increasing pressure: generally applied to gas-liquid solutions, relates the partial pressure of a gas (solute) to its molar fraction in the liquid (solvent) : Mole fraction in the liquid: ki (called henry"s law constant) depends on the solute/solvent pair and on temperature iiixkp raoult"s law, raoult"s law relates the partial pressure of a gas to its vapour pressure in liquid/liquid and liquid/solid solutions: The partial pressure exerted by solvent vapor above an ideal solution is the product of the mole fraction of solvent in the solution and the vapour pressure of the pure solvent at the given temperature.
