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 C6H12O6. at 23 Celsius and in 0.5M HCL, the following data was obtained for the disappearance of sucrose Time [C12H22O11] (M) 0 0.316 39 0.274 80 0.238 140 0.190 210 0.146 a) what is the rate order with respect to (C12H12O11) b)what is the rate constant? Using the rate constant calculate the concentration of sucrose at 39, 80, 140, 210 minutes if the initial sucrose concentration was 0.316M and the reaction was zero order in sucrose.
