The kinetics of a chemical reaction were analyzed by laboratory experiment. Lime was added to a water sample to precipitate reactant A as product P. While the water was continuously stirred, portions were withdrawn at 10-min intervals to measure the amount of A remaining. The data collected were as follows: t = 0, C0 of A = 100 mg/l; t = 10 min, C of A remaining = 55 mg/l; t = 20 min, C = 22 mg/l; t = 30, C = 8; and t = 40, C = 5. Plot graphs as shown in Figure 11.3a and b. What are the kinetics of the reaction? What is the value of the reaction-rate constant?
