Lead carbonate can be prepared by??

Lead carbonate is manufactured by passing carbon dioxide into a cold dilute solution of lead(II) acetate, or by shaking a suspension of a lead salt more soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate

slow, late, products

Explanation:

Hammond's postulate in physical organic chemistry helps to rationalize the transition states of species. For endothermic reactions, the transition states look more like the products in structure. Hence endothermic reactions which are kinetically slow have transition states which occur late in the reaction and resemble the products more closely.
