Document Summary

Vapor pressure when a liquid vaporizes within a closed container, after a time, the vapor molecules begin to. Chem 1a03 condense to the liquid state at the same rate at which liquid molecules vapor: vapor pressure of a liquid is a property resulting from an equilibrium condition. Pcl5(g), if the reaction went to completion, the final pressure would have been 2. 0 atm. Pcl3(g) + cl2(g); consider pcl5(g) exerting a pressure of 1. 0 atm, pressure: the decomposition of pcl5 is a reversible reaction that reaches an equilibrium condition. K a thermodynamic parameter characterizing the tendency for a chemical reaction or process to occur. Activity: the activity (a) of a solute, s, is given by a = [s] / [s]o a = [s] (no units) [s]o = 1 mol l-1 reference state. 1 under ideal conditions (dilute solutions of < 0. 001 m: the activity (a) of a gas, g is given by. A = pg /po a =pg (no units)
