An aqueous suspension dosage form is prepared which contains 150 mg of drug per ml of suspension. The equilibrium solubility of the drug in water is 11 g/L. The drug in solution undergoes first-order decomposition and decomposes to 75% of the initial concentration in 400 hours.
A) Determine the zero-order rate constant.
B) Assuming that the shelf-life of a drug is t10%, calculate the shelf-life.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
