Decide which of the following statements are true and which are false, concerning the kinetic molecular theory. a. The particles are in constant motion. The collisions of the particles with the walls of the container are the cause of the pressure exerted by the gas.
b. The particles are so small compared with the distances between them that the volume of the individual particles can be assumed to be zero.
c. The average kinetic energy of a collection of gas particles is assumed to be directly proportional to the Kelvin temperature of the gas.
d. The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory.
e. The particles are assumed to exert no forces on each other; they are assumed neither to attract nor to repel each other.

um i think it might be a car?

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
