Dinitrogen tetroxide (N2O4) dissociates via the reaction: N2O4 (g) ? 2NO2 (g). 3.00 × 10-2 mol N2O4 (g) is introduced into a 1.000L flask. At equilibrium, 2.36 × 10-2 mol N2O4 (g) remains. What is the equilibrium constant for this reaction?
Energy cost of dissociation was found to be 4 kWh/m3 of CO2. Calculate conversion degree of CO2 into CO and O2 in this system.
What was the chemical reaction in the body, and what substance in the liver was produced to help catalyze the reaction?
Carbon disulfide and carbon monoxide are produced when carbon is heated iwth sulfur dioxide. 5C9s) + 2SO2(g) --> CS2(l) +4CO9g)
What volume of O2, measured at 25C and 1.00atm, is expelled when 425ml of water saturated with O2 is heated from 0 to 25C?
What are the RATE LAW and k VALUE (with units) for the reaction? Assume conc. in moles per liter T or F. Feezer burn involves solid water conversion to vapor then back again.
