1.The equilibrium constant Kc for the following reaction is 5.70.
H2(g) + CO2(g) H2O(g) + CO(g)
Initially, 1.05 moles each of H2 and CO2 are injected into a 4.50 L flask. Calculate the concentration of the H2O(g) at equilibrium.
2. Consider the oxidation of ammonia NH3 by oxygen O2 to form nitrogen dioxide NO2 and water H2O :
4NH3(g) + 7O2(g) 4NO2(g) + 6H2O(l)
Suppose that in this reaction water is being formed at a rate of 15.5 moles liter-1 sec-1. At what rate (in moles liter-1 sec-1) is oxygen used up? Enter your answer as a number with one decimal place.
3.An ideal solution of toluene (vapor pressure 21 torr) and cyclohexane (vapor pressure 67 torr) in which the mole fraction of toluene is 0.45 is boiled and the vapor condensed to a liquid. What is the mole fraction of cyclohexane in the condensed liquid? |
