The condensation of Acetone (AH) in aqueous solution is catalyzed by bases, B, which react reversily with acetone to form carbanion, A- plus the rotonated base, BH+. The carbanion then reacts with a molecule of acetone to give the product. Assuming the steady state approximation is valid, determine the concentration of the carbanion and derive a rate equation for the formation of product (remember this rate equation should not include any intermediates)
HA + B ---> BH+ + A- A- + HA ---> Products
