Part D is what is needed
C. Sucrose is readily hydrolyzed i.e. broken down back to glucose and fructose by reaction with acidic solution. The hydrolysis can be monitored by measuring the angle of rotation of plane-polarized light passing through the solution because the concentration of sucrose can be inferred from this angle. An experiment on the hydrolysis of sucrose in 0.5 M HCl(aq) produced the following data: t/min 0 (sucrose) 0.316 /M 14 0.300 39 0.274 60 80 0.256...
