Question

Sucrose (C₁₂H₂₂O₁₁), commonly known as table sugar, reacts in dilute acid solutions to form two simpler sugars, glucose and fructose, both of which have the formula C₆H₂₂O₆. At 23 °C and in 0.5 M HCl, the following data were obtained for the disappearance of sucrose:

(a) Is the reaction first order or second order with respect to [C₁₂H₂₂O₁₁]? (b) What is the rate constant? (c) Using this rate constant, calculate the concentration of sucrose at 39, 80, 140, and 210 min if the initial sucrose concentration was 0.316 M and the reaction were zero order in sucrose.
