TG–MS and TR–XRD studies
can be written as: (2) The above equation pertains to a single step reaction kinetics, but quite often the solid state reactions contain complex reaction steps and a single rate equation is unable to explain the complexities of solid state
question. The sampling and analytical design must not interfere with the flowability of matter inside the reactor. Additionally, reaction kinetics are expected to be fast given the residence time is short inside a flow reactor. This calls for raising the

the α versus t data corresponding to the ranges, α = 0.15–0.45 and α = 0.5–0.95, showed that the both ranges gave the best fits to contracting square model but with different rate constants, k 1 and k 2 . Description of reaction kinetics using
