The following data was obtained on the rate of hydrolysis of 17% sucrose in 0.099 M HCl aqueous solutions at 35 C.
t/min: 9.82, 59.60, 93.18, 142.9, 294.8, 589.4
Sucrose remaining, %: 96.5, 80.3, 71.0, 59.1, 32.8 11.1
What is the order of the reaction with respect to sucrose and the value of the rate constant k?
