Answer to Question #137652 in Physical Chemistry for mastmalang

Question

Calculate the rotational partition function for HCl at 298 K when the moment of inertia is 2.7 x 10e-47 kgm^2 ?

Answer 1

The rotational partition function for a heteronuclear diatomic molecule  z_rot = 8π²IkT/h² , I - moment of inertia. z_rot = 8*3.14²*2.7 * 10^-47*1.38*10^-23*298/(6.63*10⁻³⁴)²=19.92
