As agno3 dissolves how does the temperature of the solution change

AGNO3 (s) >   Ag^+ (aq) + NO3^-  (aq)    {  inorganic reaction }

the dissolution process is endothermic ( absorb energy ) , the crystallization process is exothermic ( release energy )

the temperature will go down and feel cool as  the solute dissolves
the rate of crystallization and rate of dissolution will be equal or the same at equilibrium. the rate of dissolution will initially increase  , because the process needs to absorb energy to occur , by heating the solution energy is added and the solubility of the solute will decreases more silver nitrate .

I'm not sure but i will try to find out
