All liquids evaporate to a certain extent. the pressure exerted by the gas phase in equilibrium with the liquid is called vapor pressure, pvap. the vapor pressure of a particular substance is determined by the strength of the intermolecular forces. but for any given substance, the vapor pressure only changes with temperature. the clausius-clapeyron equation expresses the relationship between vapor pressure and temperature:

Apure solvent has a vapor pressure the vapor pressure of a solution. a. equal to b. lower than c. higher than

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
