Question

Calculate the entropy for a system consisting of 10 particles distributed over four energy levels with occupancies of (5, 3, 2, 0) 1. 2. If there exists two excited states at energies of 0.72 and 1.24 kJ mol above the ground state of a system, 0 kJ mol. What would be the percentage of particles occupying each state at equilibrium when the temperature is 300 K 3. Evaluate q for a nitrogen molecule (molecular weight 28.0134 g mol) at 25 °C when occupying a volume of IL 4. Calculate the molar entropy of argon gas (M, 39.948 g mol) at 298.15 K and 1 bar of pressure.
