Which one of the following is correct about following reaction if iron is not 100% pure?2Fe+3H2O+02 → Fe2O3.3H2O
Correct answer: B. Very slow reaction
- A. Very fast reaction
- B. Very slow reaction
- C. Moderately reaction
- D. Not predicted
Explanation
It is rusting of iron so it is very slow process

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.
