Which of the following statements is not correct about rusting of iron?
- A Coating of iron surface by tin prevents rusting, even if the tin coating is peeling off.
- B When \(\mathrm{pH}\) lies above \(9\) or \(10\) , rusting of iron does not take place.
- C Dissolved acidic oxides \(\mathrm{SO}_2, \mathrm{NO}_2\) in water act as catalyst in the process of rusting.
- D Rusting of iron is envisaged as setting up of electrochemical cell on the surface of iron object.
Answer & Solution
Correct Answer
(A) Coating of iron surface by tin prevents rusting, even if the tin coating is peeling off.
Step-by-step Solution
Detailed explanation
As tin coating is peeled off, then iron is exposed to atmosphere.

- Observe the following reactions at T(K):
I. \( A \rightarrow \text{products} \)
II. \( 5Br^{-}(aq) + BrO_{3}^{-}(aq) + 6H^{+}(aq) \rightarrow 3Br_{2}(aq) + 3H_{2}O(l) \)
Both the reactions are started at 10.00 am. The rates of these reactions at 10.10 am are same. The value of \( -\frac{\Delta[Br^{-}]}{\Delta t} \) at 10.10 am is \( 2 \times 10^{-4} \text{ mol L}^{-1} \text{Min}^{-1} \). The concentration of A at 10.10 am is \( 10^{-1} \text{ mol L}^{-1} \). What is the first order rate constant (in \( min^{-1} \)) of reaction I?JEE Mains 2026 Medium - Match List - I with List - II.
