Chemistry - Chemical Kinetics Question with Solution | TestHub

It is an example of pseudo unimolecular reaction where molecularity $\ge 2$ but order of reaction is one. Rate $=k[$ Sugar $]\left[{\mathrm{H}}_2\mathrm{O}\right]$ In the reaction, water is present in excess and its concentration is taken to be constant, thus the reaction becomes independent of $\left[{\mathrm{H}}_2\mathrm{O}\right]$ and is pseudo first order.
