# Gases, Kinetics, and Chemical Equilibrium

 Mean free path is: The distance traveled by a gas molecule between collisions. Four ideal gas characteristics gas molecules of zero volumegas molecules exert no forces on other repulsive forces due to collisionsgas molecules make completely elastic collisionsthe average kinetic energy of gas molecules is directly proportional to the temperature of the gas The ideal gas law is: PV = nRT R = 0.08206 L atm K-1 mol-1 Charle's law says that: volume is proportional to temperature at constant pressure Boyle's law says that: volume is inversely proportional to pressure at constant temperature Avogadro's law states that: volume is proportional to the number of moles at constant temperature and pressure Solving for the partial pressure of a particular gas: χa * Ptotal = Pa Dalton's law of partial pressures states that: the total pressure is equal to the sum of the partial pressures Ptotal = Pa + Pb + Pc + ... + Pn Relationship between velocity and mass of two gases v1 / v2 = √m2 / √m1 Real gases differ from ideal gases because they exhibit these behaviors Vreal > VidealPreal < Pideal For a new molecule to be formed according to the collision theory 2 requirements must be met: molecules collide with enough kinetic energy (to overcome activation energy)molecules collide in the correct orientation What is the relationship between temperature and rate of reaction Temperature and rate of reaction is proportional. As the temperature increases so does the rate of the reaction.
