N2(g)+O2(g)<->2NO(g) Kc= 1.7x10^-3
Calculate the equilibrium concentrations if the initial concentrations are 2.31 M N2 and 0.59M O2 . (This N2/O2 concentration ratio is the ratio found in air.)
The vapor pressure of water above this solution is found to be 0.3624 atm at 348.0 K. The vapor pressure of pure water at this temperature is 0.3804 atm.
then we cooled in an ice bath. then we washed it with water. and then added bicarbonate to netralize any acetic acid or sulfuric acid present. then we did an an extraction.
