Question: which among the following reactions is an example of pseudo first order reaction?
Answer: For example, the hydrolysis of esters by dilute mineral acids follows pseudo-first order kinetics where the concentration of water is present in large excess: CH3COOCH3 + H2O → CH3COOH + CH3OH. The hydrolysis of sucrose (C12H22O11) in acid solution is often cited as a first-order reaction with rate r = k[C12H22O11].
