Calculate the temperature values at which the molecules of the first two members of the homologous series, C_(n) H_(2n+2) will have the same rms speed as CO_(2) gas at 770 K .The normal b.p. of n - butaneis 273 K. Assuming idealgas behaviour of n-butane upto this temperature , calculate the mean velocity and the most probable velocity of its molecules at this temperature.
