In some reactions, a product formed acts as a catalyst. This phenomenon is called:
Correct answer: D. Autocatalysis
- A. Negative catalysis
- B. Heterogeneous catalysis
- C. Activation of catalyst
- D. Autocatalysis
Explanation
If product formed act as a catalyst is called autocatalyst and reaction is called auto catalysis.One of the simplest examples of this is in the oxidation of a solution of oxalic acid by an acidified solution of potassium manganate (VII) (potassium permanganate).The reaction is very slow at room temperature.

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.
