in the present study, silver nanoparticles, Ag-NPs have been prepared by a Aqueous Seeds Extract of Ziziphus Spina-Christi as reducing agent and a solution of silver nitrate (AgNO3). From poly nuclear growth rate model, the rate of growth was found to be equals 0.0011 nm/min. Different morphologies of silver colloids could be obtained using different temperature. The reduction kinetic of Ag+ was followed the second order model. Also, the synthesis of Ag-NPs was endothermic reaction and spontaneous at medium and high temperature while non spontaneous at low temperature. Gibbs free energy of formation was not constant and was changed with radios of Ag-NPs
