Vedclass · Answer

(A) The hydrolysis of sucrose is a reaction that can be catalyzed by either an acid or an enzyme (sucrase). Enzymes are biological catalysts that lower the activation energy of a reaction significantly compared to inorganic catalysts or acid-catalyzed reactions. For the hydrolysis of sucrose,the activation energy with acid catalysis is approximately $6.22 \ kJ \ mol^{-1}$,while the activation energy with the enzyme sucrase is significantly lower,approximately $2.15 \ kJ \ mol^{-1}$. Therefore,$X = 6.22$ and $Y = 2.15$.

Activation energy for the hydrolysis of sucrose by acid is $X \ kJ \ mol^{-1}$ whereas activation energy for the hydrolysis of sucrose by sucrase is $Y \ kJ \ mol^{-1}$. $X$ and $Y$ respectively are
