The enthalpy of solution for $$\mathrm { AgNO } _ { 3 }$$ is +22.8 kJ/mol.
a. Write the equation that represents the dissolution of $$\mathrm { AgNO } _ { 3 }$$ in water.
b. Is the dissolution process endothermic or exothermic? Is the crystallization process endothermic or exothermic?
c. As $$\mathrm { AgNO } _ { 3 }$$ dissolves, what change occurs in the temperature of the solution?
d. When the system is at equilibrium, how do the rates of dissolution and crystallization compare?
e. If the solution is then heated, how will the rates of dissolution and crystallization be affected? Why?
f. How will the increased temperature affect the amount of solute that can be dissolved?
g. If the solution is allowed to reach equilibrium and is then cooled, how will the system be affected?
