Kinetic of Dehydration of CuSO4+5H2O

Abstract

Thermal decomposition of CuSO₄·5H₂O was studied under non-isothermal conditions in air. The kinetic of particular stages of CuSO₄·5H₂O decomposition were evaluated from the dynamic weight loss data by the means of integral method and differential method. The values of the activation energy E, the pre-exponential factor A of each stages of the thermal decomposition were calculated. The entropy of activation (ΔS^≠), the enthalpy of activation (ΔH^≠), the free energy of activation (ΔG^≠) and kinetic compensation effect were also studied.
