Oxygen at 150 K and 41.64 atm has a tabulated specific volume of 4.684 cm3/g and a specific internal energy of 1706 J/mol.(a) The figure 1706 J/mol is not the true internal energy of one g-mole of oxygen gas at 150 K and 41.64 atm. Why not? In a sentence, state the correct physical significance of that figure. (The term “reference state” should appear in your statement.)(b) Calculate the specific enthalpy of O2 (J/mol) at 150 K and 41.64 atm, and state the physical significance of this figure. What can you say about the reference state used to calculate it?
It has been experimentally determined that the heat of combustion of benzene at constant volume is: ΔU ° rxn = -3265.6 kj, at 298K and the heat of combustion at constant pressure is: ΔH ° rxn = -3261.9 kj.

1 kg of benzene is poured into a flask and heated to 353 K (the boiling point of benzeneat 1 atm.) using a heating element that has a power of 700 W (we ignore thatit's probably not so healthy and smart to do). After 5 minutes, when the benzene has stoodboiling point, the heating element is taken up, and the remaining mass of benzene in the flaskmeasured at 470 grams. Determine the enthalpy of vaporization of benzene.

One mole of a perfect monatomic gas, initially at 300 K and a pressure 15.0 atm, expands to afinal pressure of 1.00 atm. Consider the expansion via each of the following paths: (a)isothermal and reversible, (b) isothermal and irreversible, (c) adiabatic and reversible, (d)adiabatic and irreversible. In these irreversible processes, the expansion occurs against anexternal pressure of 1.00 atm. For each case, calculate the values of q, w, ΔU and ΔH.
For H2(g), Cp,m is nearly constant at 20.4 J/mol K for temperatures in the range of 100 K to 400 K and low or moderate temperatures.

After you solve the problem, state whether T of the H2 would increase or decrease during the process, and state your reasoning.
Consider one mole of an ideal monoatomic gas at STP and confined in a volume V1. You would like to increase its temperature by an amount ΔT.a) Where will you provide less heat to achieve your objective; at constant volume process or at constant pressure process? Give your reasoning without using or referring to any formula.b) We can achieve the same objective along an adiabatic process; how do we do it keeping in mind that there is no heat exchanged in an adiabatic process?c) Express the work done by the gas in the three processes; the question is not merely to write the expressions but you must show briefly how they are obtained.
