If the AHsolution, KI = 15 kJ/mol, then calculate the lattice energy for potassium iodide using the data from a standard reference table shown here.
K+
11
A Hhydration
-335kJ/mol
-293kJ/mol

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

i think   the answer is c hope i'm right

the ratio of the conjugate base to the acid required to attain the desired ph.
