Explanation:
Dalton’s atomic theory is based on law of constant composition and law of conservation of mass.
One of the postulates of this theory is that rearrangement of atoms occurs during a chemical reaction. In other words, only rearrangement of elements occurs during a chemical reaction and elements remain the same.
So, among the given, the following reaction undergoes rearrangement of elements.
N2+O2→2NO
SO, only the above reaction is possible as per Dalton’s atomic theory.
