$5$ milli-moles of a solid $A$ was dissolved in $5$ moles of $H_2O$ . On adding to the solvent, $A$  starts polymerising into another insoluble solid following zero order kinetics. On adding $6$ milli-moles of another solid solute $C$ (after $20$ minute) the polymerisation completely stops. The  nsoluble solid polymer is removed and the resulting solution was cooled to a temperature less  than $- 0.186\,^oC$ (melting point of solution) to cause solidification of some liquid water. Calculate the value of $'X'$ if rate constant for polymerisation reaction is represented as $10^{-X}\,moles/minute$ . $[K_f(H_2O) = 1.86\, K\,- Kg\,mole^{-1}]$
