5 milli-moles of a solid A was dissolved in 5 moles of H_(2)O. On adding to the solvent , A sstarts spolymerising into another insoluble solid following zero order kinetics. On adding 6 milli-moles of another solid solute C (after 20 minute) the polymerisation compeletly stops. The insoluble solid polymer is removed and the resulting solution was cooled tova temperature less then -0.186^(@) C(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)mole//minute. [K_(f)(H_(2)O)=1.86 K-kg "mole"^(-1)] |
