A system of N particles has, among others, two energy levels with g₁ = 2, g₂ = 3, U₁ = 41.84 kJ mol^-1 and U₂ = 58.58 kJ mol-1. Calculate the ratio of the number of particles in the two energy states at 1000 K.

By using conventional state theory, for elementary biomolecular reactions, determine the molar entropy of activation ΔS⁺ .

Two containers X and Y have equal fixed  number of particles. Container X is maintained at constant temperature while container Y is maintained at constant temperature and pressure. What statistical ensemble will you use to best describe the properties of particles in the two containers?

According to STIRLING approximation the value of term :  ln N! is given by :

The unit of the molecular partition function is :
