Abstract
Non-isothermal decomposition kinetics of LaCrO4, PrCrO4, and NdCrO4 have been investigated. In each case, first order decomposition takes place. The energy of activation, Ea* has been evaluated by applying five different computational procedures based on the data of TG, DTA, and DTG. These values are fairly in good agreement with each other and the average activation energies per mole of the compounds are : LaCrO4: 240 kcal, PrCrO4: 180 kcal and NdCrO4: 170 kcal. The above trend in Ea* has been rationalized by taking into consideration the packing of atoms in rare earth chromates(V).
