Answer : The correct option is,
Explanation :
Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.
The general representation of decomposition reaction is :
From the given options,
this reaction a decomposition reaction in which a single nitrogen dioxide decomposes to give oxygen gas and nitrogen gas as a product.
While the other reactions,
this reaction is a combination reaction in which the two or more molecules combine to form a larger single molecule as a product.
this is a double displacement reaction in which the cation and the anion of the two reactant exchange their places to give two another compounds as a product.
this is a single displacement reaction in which the more reactive metal displaces the least reaction metal from its compound.
Hence, the decomposition reaction will be,

For the net reaction: 2AB + 2C → A2 + 2BC, the following slow first steps have been proposed.
(1) AB → A + B
(2) 2C + AB → AC + BC
(3) 2AB → A₂ + 2B
(4) C + AB → BC + A
What rate law is predicted by each of these steps?
Answer : The rate law expression for the following reactions are:
(1)
(2)
(3)
(4)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The general reaction is:
The general rate law expression for the reaction is:
where,
a = order with respect to A
b = order with respect to B
R = rate law
k = rate constant
and
= concentration of A and B reactant
