- Consider the following reaction CS2(g) + 3O2(g) → CO2(g) + 2SO2(g) A mixture containing only CS2(g) and excess O2(g) at a total pressure of 100 kPa is placed in a sealed vessel. After the reaction is completed and the vessel is cooled to the initial temperature, the total pressure in the vessel drops to 80 kPa. What is the mole fraction of CO2(g) in the final mixture?arrow_forwardA chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?arrow_forwardP1arrow_forward

The predominant forms of heavy metals (Zn, Pb, Fe, Cu, Ni, etc.) in aerobic sediments are the carbonates and the oxide or hydroxide forms. An important consideration in modeling the sediment is the stable chemical form of the metal in question. Consider the reaction: AG = 25 kJ/mol Pb(OH)₂ (s) + CO₂(aq) → PbCO₂ (s) + H₂O a.
