Which one of the following is correct about following reaction if iron is not 100% pure?2Fe+3H2O+O2 → Fe2O3.3H2O
Correct answer: B. Very slow reaction
- A. Very fast reaction
- B. Very slow reaction
- C. Moderately reactive
- D. Not predicted
Explanation
Conversely, if the iron used in the reaction is not pure and contains substances that inhibit or interfere with the reaction, it could lead to a very slow reaction. These impurities or contaminants might act as inhibitors, slowing down the reaction rate.

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.
