Kinetic study of the solid phase reaction of ammonium nitrate and copper oxide by the use of fast X-ray diffraction.

The solid state reaction of ammonium nitrate and copper oxide was studied by the use of energy dispersive and angle dispersive x-ray diffraction. The reaction takes place within the temperature interval 110 to 150 degree C and consists of two steps. The product of these consecutive reactions is the diammine copper complex. The relative concentrations of the species involved were evaluated by summing up difference x-ray spectra. The resulting curves were analyzed by a computer programm to obtain the kinetic constants of the reactions.
