Inversion of cane sugar is pseudo unimolecular reaction

Pseudo unimolecular reactions:
Consider the following acid catalysed reactions:

1. Hydrolysis of ethyl acetate:

Rate constant is the rate of reaction when the concentration of each reaction is taken as unity. ... The reaction rate is expressed in terms of chemical composition of the reacting species. i. The hydrolysis of an ester such as ethyl acetate in the presence of a mineral acid gives acetic acid andethyl alcohol.

CH₃COOC₂H₅ + H₂O + H⁺ ———–>CH₃COOH + C₂H₅OH

2. Inversion of cane sugar:

The Inversion of Cane Sugar. Monday's Molecule #46 was the chemical reaction shown above. This is an historically important reaction that contributed to our understanding of catalysis. The reaction shows the hydrolysis of sucrose to glucose and fructose in an acid solution.

C₁₂H₂₂O₁₁ + H₂O + H⁺ —————> C₆H₁₂O₆ + C₆H₁₂O₆
