The temperature dependence of partition functions are as follows: qtranslation ∝ T3/2                            qvibration ∝ T0 qrotation ∝ T (linear molecule)     qrotation ∝ T3/2 (non-linear molecule) According to the conventional transition state theory (CTST), the temperature dependence of the Arrhenius pre-exponential factorfor a reaction of the type given below is linear molecule + linear molecule ⇆ non-linear transition state → products
