(b) The esterification reaction above was carried out in the presence of hydrochloric acid as the catalyst. State the effect on the equilibrium position and the rate of attainment of equilibrium if the concentration of the acid catalyst were to be increased. (c) (i) Identify which bonds are broken and which bonds are made in the esterification reaction. Bonds broken: Bonds made: (ii) Explain why AH for this reaction is not exactly zero. (A calculation is not required.)
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
