Problem: Sucrose (C12H22O11 ), which is 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 oC and in 0.5 M  HCl, the following data were obtained for the disappearance of sucrose:Time  (min) C12H22O11 (M)00.316390.274800.2381400.1902100.146Using the rate constant, calculate the concentration of sucrose at 80 min if the initial sucrose concentration were 0.316 M and the reaction were zero order in sucrose.

The integrated rate law for a zero order reaction is as follows:

$\boxed{{\mathbf{\left[}\mathbf{A}\mathbf{\right]}}_{\mathbf{t}}\mathbf{ }\mathbf{=}\mathbf{ }\mathbf{-}\mathbf{kt}\mathbf{ }\mathbf{+}\mathbf{ }{\mathbf{\left[}\mathbf{A}\mathbf{\right]}}_{\mathbf{0}}}$

where:

[A]_t = concentration at time t 

k = rate constant

t = time, [A]₀ = initial concentration.
