Values of the specific internal energy of bromine at three conditions are listed here. State T(K) P(bar) ˆ V ( L / mol ) Vˆ(L/mol) ˆ U ( kJ / mol ) Uˆ(kJ/mol) Liquid 300 0.310 0.0516 −28.24 Vapor 300 0.310 79.94 0.000 Vapor 340 1.33 20.92 1.38 What reference state was used to generate the listed specific internal energies? Calculate Δ ˆ U ( kJ / mol ) ΔUˆ(kJ/mol) for a process in which bromine vapor at 300 K is condensed at constant pressure. Then calculate Δ ˆ H ( kJ / mol ) ΔHˆ(kJ/mol) for the same process. (See Example 7.4-1.) Finally, calculate ΔH(kJ) for 5.00 mol of bromine undergoing the process. Bromine vapor in a 5.00-liter container at 300 K and 0.205 bar is to be heated to 340 K. Calculate the heat (kJ) that must be transferred to the gas to achieve the desired temperature increase, assuming that ˆ U Uˆ is independent of pressure. In reality, more heat than the amount calculated in Part (c) would have to be transferred to the container to raise the gas temperature by 40 K. State two reasons for this.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.
