(b) Consider a system of distinguishable particles having only three non-degenerate energy levels separated by an energy that is equal to the value kT at 25.0 K. Calculate: (a) the ratio of populations in the states at: (1) 1.00 K, (2) 25.0 K, and (3) 100 K; (b) the molecular partition function at 25.0 K; (c) the molar energy at 25.0 K; (d) the molar heat capacity at 25.0 K; (e) the molar entropy at 25.0 K.

What are the first three quantum numbers for the electrons located in subshell 2s?

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
