Consider the following reactions and their equilibrium constants at 303 K. PCl5(g) equilibrium reaction arrow 1/4 P4(g) + 5/2 Cl2(g); Kc = 1.18 ✕ 10−21 1/4 P4(g) + 3/2 Cl2(g) equilibrium reaction arrow PCl3(g); Kc = 2.28 ✕ 1026 Calculate Kc for PCl5(g) equilibrium reaction arrow PCl3(g) + Cl2(g) at the same temperature.

What is the subscript for oxygen in its molecular formula

Tell me the iupac names of the following alcohols:

)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.
