Which of the following reactions is possible according to Dalton's atomic theory? View Available Hint (s) Which of the following reactions is possible according to Dalton's atomic theory? N2→O2 N2+O2→2NO CO2→NO2 H2O→H2S

N2+O2→2NO

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.
