rate is also increased following Arrhenius reaction rate model for heterogeneous media. Hence majority
of input energy is utilised for energy required for dissociation of ZnO and the re-radiation loss. This
results in a drop of sensible heat loss in the reactors
The mean reactor efficiency of the reactor is defined as ratio of useful energy of the reaction to the input
energy and it is found out to be 15.5%. The useful energy is a sum of heat of reaction and sensible heat
absorbed by ZnO particles.
The mean reactor efficiency is given by
