As the hydrolysis of ester proceeds, more and more acid is formed giving a:
Correct answer: A. Rising curve
- A. Rising curve
- B. Falling curve
- C. Straight line
- D. None of these
Explanation
During the hydrolysis of an ester, ester bonds are broken down into their respective carboxylic acid and alcohol components. As the hydrolysis reaction proceeds, more and more ester molecules are converted into their acid forms. Consequently, the concentration of acid increases over time. Producing a rising curve.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
