A prescription for a liquid aspirin preparation. It Is to contain 325mg/5ml or 6.5g/100ml. The solubility of aspirin at 25oC is 0.33g/100ml; therefore, the preparation will definitely be a suspension. The other ingredients in the prescription will definitely be a suspension. The other ingredients in the prescription cause the product to have a pH of 6.0. the first- order rate constant for aspirin degradation in this solution is 4.5X 10-6 sec-1. Calculate the zero order rate constant. Determine the shelf life (t90)​
