Suggest a name for the reaction that takes place when sucrose reacts with water to give glucose and fructose.
If no catalyst is added in reaction Z, the reaction is extremely slow. Label the Boltzmann distribution to show the effect of adding a catalyst to the sample of sucrose and water molecules at constant temperature. Explain your labelled diagram.
Explain what is meant by the term chiral centre.
On the fructose molecule diagram, mark all the chiral centres with an asterisk (*).
Determine the empirical formula of fructose.
Explain what is meant by the term enthalpy change of combustion.
Write the equation for the complete combustion of sucrose.
Use the data in the table to calculate the enthalpy change for the reaction when sucrose reacts with water, $\Delta H_r$. You should draw a labelled Hess' cycle to present your working.
