The solubility of CuBr ( s ) at equilibrium to be calculated. Concept introduction: The constant K sp is known as solubility product or solubility product constant. It is equilibrium constant and for a given solid, it has a particular value at a given temperature. However, the solubility is equilibrium position. The solubility product expression comprises of product of the ion concentrations.

Question

Using the graphs could you help me explain the answers. I assumed that both graphs are proportional to the inverse of time, I think. Could you please help me.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
