Dependence of the conversion period on temperature. Temperature considerably affects the reaction rate. In NaOH media, an apparent activation energy (Ea) of 60.3 kJ mol-1 was obtained, and in Ca(OH)2 the obtained apparent activation energy (Ea) was 74.4 kJ mol-1. These values are within the range of chemical control.
