The following data were obtained on the rate of lactose decomposition as a function of acid and lactose concentration. Using this information, determine the rate law expression and the value of rate constant for the acid-based hydrolysis of lactose.
Run [lactose]o (M) [H+]o (M) Initial rate (1/M·s)
1 0.01 0.001 0.00116
2 0.02 0.001 0.00232
3 0.01 0.004 0.00464
