Possibility of a catalytic reaction of H/sub 2/ + Cl/sub 2/
It is shown that the amount of conversion of hydrogen in its reaction with chlorine in a mixture passing through a layer of activated carbon at 200/degrees/C corresponds to an effective rate constant that is three orders of magnitude larger than that calculated for the homogeneous reaction in the regime of equilibrium dissociation of chlorine. On the basis of this, the conclusion is drawn that a heterogeneous catalytic process predominates in this case. It is established that with an increase in the temperature up to 300/degrees/, the rate of the homogeneous reaction, having the larger temperature coefficient, becomes commensurate with the heterogeneous rate. In the general case, the ratio of the rates of chlorination for the homogeneous, chain mechanism and for the heterogeneous catalytic reaction mechanism depend on the experimental conditions.
