3NO2 (g) + H2O (l) ↔ 2HNO3 (aq) + NO (g) Jika direaksikan 980 kg gas NO2 dengan 450 liter air, setelah 40 % gas NO2 bereaksi sistim mengalami kesetimbangan. A. Tentukan komposisi senyawa dalam tanki saat kesetimbangan (skor 5) b. Jika volume tanki 1000 liter, tentukan nilai konstanta kesetimbangan Kc (skor 10) c. Jika tekanan total tanki 24 atm, tentukan nilai konstanta kesetimbangan Kp (skor 5)

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.

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
