Read the passage carefully and answer the questions based on the passage:
The number of reacting species (atoms, ions or molecules) taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction is called molecularity of a reaction. In the rate equation Rate \(=k[\mathrm{~A}]^x[\mathrm{~B}]^y\)
\(x\) and \(y\) indicate how sensitive the rate is to the change in concentration of \(A\) and \(B\), respectively. Sum of these exponents, i.e., \(x +y\) gives the overall order of a reaction where \(x\) and \(y\) represent the order with respect to the reactants A and B respectively. Hence, the sum of powers of the concentration of the reactants in the rate law expression is called the order of that chemical reaction. For a first order reaction, the concentration of the reactant varies as \([\mathrm{R}]=[\mathrm{R}]_0 e^{-k t}\)
The initial concentration of \(\mathrm{N}_2 \mathrm{O}_5\) in the following first order reaction
\(\mathrm{N}_2 \mathrm{O}_5(g) \rightarrow 2 \mathrm{NO}_2(g)+1 / 2 \mathrm{O}_2(g)\)

Which of the statements given below are correct with reference to corrosion:
(A) Corrosion covers the surfaces of metallic objects with oxides or other salts.

(C) Rust is hydrated ferric oxide.
(D) A sacrificial electrode is used to save an object from corrosion.
