β¦ Synopsis
Replacement of N 2 by CO in H 2 + 02 + N 2 mixtures undergoing slow reaction at 500Β°C causes a marked increase in the reaction rate and a decrease in the induction period, expressed as the time to half maximum rate. A detailed interpretation using a computer treatment gives k24/klo 1/2 = 0.42 Β± 0.03 (litre tool -1 s--l) 112 from which k24 = 1.9 Γ 104 litre tool -1 s -1. Arrhenius parameters E24 = 96.0 kJ mo1-1, A = 5.8 Γ 1010 litre tool -1 s -1 are suggested. ' Reaction numbers have been chosen to maintain consistency with previous papers.
