KINETICS OF THE THERMAL DECOMPOSITION OF NICKEL SULFATE.

Article abstract of DOI:10.1246/bcsj.56.3294

The rate of thermal decomposition of nickel sulfate was measured in the temperature range from 1003 K to 1078 K. When a powder sample was used, this reaction was characterized as a contracting volume reaction, with apparent activation energy of 296 kJ mol** minus **1. The gaseous products were sulfur trioxide, sulfur dioxide, and oxygen. The composition of the gaseous products was near equilibrium in regard to the reaction, SO//3 equals SO//2 plus 1/2 O//2, because the nickel oxide formed had high catalytic activity for this reaction.
