The reaction
is the basis of a suggested method for removal of SO2 from power-plant stack gases. The standard free energy of each substance is given in Appendix C.
(a) What is the equilibrium constant for the reaction at 298 K?
(b) In principle, is this reaction a feasible method of removing SO2?
(c) If PSO2 = PH2S and the vapor pressure of water is 25 torr, calculate the equilibrium SO2 pressure in the system at 298 K.
(d) Would you expect the process to be more or less effective at higher temperatures?

A reinforced concrete beam having the cross section shown is on a simple span of 28ft. It carries uniform service loads of 3.60 kips/ft live load and 2.20 kips/ft dead load. Check the adequacy of the beam with respect to the moment.
Suppose that the value of D is 800 when S, ρ, and vare expressed in SI base units. By converting units determine thevalue of D when S, ρ, v are expressed in U.S customary units.
Geometric design and construction of a new two-lane two-way road has been recently completed and now it is time for design pavement near Ballarat, Victoria.
A lake has a water level which is used to determine if watering restrictions need to be implemented for the neighboring city. Water levels are measured on a weekly basis, and restrictions are placed if the lake level drops below 1060 ft.
