Every valentine’s day, CVS sells chocolate-covered cherries. The chocolate-covered cherries are like a mini cake with a cherry inside. The cake comprises a combination of sucrose (powder sugar), butter, cherry juice, and an enzyme (invertase). Time (hours) Sucrose Concentration (g/cm3) 0 0.844 24 0.681 48 0.550 96 0.357 192 0.153 While stored at 5.00C, the sucrose hydrolyzes to produce glucose and fructose. The mixture of the glucose and fructose is a liquid called invert sugar. Below you will find the concentration of sucrose in the cake as a function of time. For the cherries to be edible, the 85% of the sucrose must be hydrolyzed. Before you start to answer the question, create a data table that comprises sucrose concentration in units of moles per liter.

While stored at 5.00C, the sucrose hydrolyzes to produce glucose and fructose. The mixture of the glucose and fructose is a liquid called invert sugar. Below you will find the concentration of sucrose in the cake as a function of time. For the cherries to be edible, the 85% of the sucrose must be hydrolyzed.
Before you start to answer the question, create a data table that comprises sucrose concentration in units of moles per liter.
- Write the
chemical reaction that demonstrates the hydrolysis of sucrose.
- With the data, determine how long it will take for 85% of the sucrose to be converted into glucose and fructose. You must show your work.
- What would happen if the invertase was not included in the recipe?
- Create a graph that demonstrates how the reaction will behave if the storage temperature increases as a function of time.
