N2 + O2 —> 2NO b) A student injects N2(g)and O2(g) into a previously evacuated, rigid 10.0L vessel and raises the temperature of the vessel to 500K. At this temperature the
initial pressures of N2(g) is 7.0 atm and 5.50 atm, respectively. The system is allowed to reach equilibrium. The partial pressure of NO(g) at equilibrium is 3.00
atm. Calculate the partial pressures at equilibrium for N2(e) and O2(g)

Compare and contrast physical changes with chemical changes.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
