The degree of freedom of mixture of two ...

The degree of freedom of mixture of two ideal gases having moles `n_1` and `n,_2` and degree of freedom `f_1` and `f_2` respectively, is

A

`[f_(mix) = (n_1f_1 + n_2f_2) / (1/n_1 + 1/n_2)]`

B

`[f_(mix) = (n_1f_2 + n_2f_1) / (n_1 + n_2)]`

C

`[f_(mix) = (n_1f_1 + n_2f_2) / (n_1 + n_2)]`

D

`[f_(mix) = (n_1/f_1) +( n_2/f_2) / (n_1 + n_2)]`

The total energy of molecules is divided equally amongst the various degrees of freedom of a molecule. The distribution of kinetic energy along x, y, z axis are E_(K_(x)), E_(K_(y)), E_(K_(z)) Total K.e =E_(K_(x)) + E_(K_(y)) + E_(K_(z)) Since the motion of molecule is equally probable in all the three directions, therefore E_(K_(x)) = E_(K_(y)) = E_(K_(z)) =1/3 E_(K) =1/3 xx 3/2 kT = 1/2 kT , where k =R/N_(A) = Botzman constant. K.E. = 1/2 kT per molecule or =1/2 RT per mole. In vibration motion, molecules possess both kinetic energy as well as potential energy. This means energy of vibration involves two degrees of fiuedom. Vibration energy =2 xx 1/2kT =2 xx 1/2RT [ therefore two degrees of freedom per mole] If the gas molecules have n_(1) translational degrees of freedom, n_2 rotational degrees of freedom and n_(3) vibrational degrees of freedom, that total energy = n_(1)[(kT)/2] + n_(2) [(kT)/2] + n_(3) [(kT)/2] xx 2 Where 'n' is atomicity of gas.
