Calculate the overall complex dissociation equilibrium constant for the Cu(NH3)42+ ion, given that β4 for this complex is 2.1 x 1013.
β4 = 2.1 × 1013
The overall complex dissociation equilibrium constant is the reciprocal of the overall stability constant, β4.
1/β4 = 1 / 2.1 × 1013
= 4.7 x 10-14
Vapour pressure of pure acetone and chloroform at 328 K are 741.8 mm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot ptotal' pchloroform' and pacetoneas a function of xacetone. The experimental data observed for different compositions of mixture is.
