1 CHE 131 Lecture 25 – Gas density, partial pressures, real gases Prof. Wong Chapter 10: pp. 457-467. Combined Gas Law At constant mass of gas V α T/P V = d × (T/P) where d is a proportionality constant (VP)/T = d V 1 P 1 = d = V 2 P 2 T 1 T 2 V 1 P 1 = V 2 P 2 T 1 T 2

2 Ideal Gas Law V α (n × T)/P V = R × (n × T)/P where R is proportionality constant P × V = n × R × T Conditions at 0ºC and 1 atm are referred to as standard temperature and pressure conditions (STP). p.451
3 How does Kinetic Molecular Theory account for the ideal gas law? Boyle’s : Decreasing V increases the frequency of particle collisions with the wall, increasing P. Charles’s: Increasing T increases the speed of particles. P, V term must increase to maintain constant P. Avogadro’s: Increasing quantity of gas increases the frequency of particle collisions with the Ideal Gas Constant R – universal gas constant, same for all gaseous substances!
