Question:
(a) A dispersion colloid can be coagulated with the following electrolytes:51 mmol·dm-3 NaCl,0.65mmol·dm-3 CaCl2 and 0.095mmol·dm-3AlCl3. What is the
charge of the dispersed particle?
(b) Suppose a first order reaction has a half-life that is 8700h(one-year) at 27°C.
The activation energy is 120kJ/mol. What is the half-life if a catalystis added that has the effect of reducing the activation energy, to 100kJ/mole? Calculate
the value of the pre-exponential factor for this reaction.
