Why does molecule participate in chemical reaction when in it's definition, it's clearly written that it has independent existence and it does not participate in chemical reaction? And if this definition was proved wrong after sometime, then why we still use this "does not participate in chemical reaction" in its definition?

Answer:
Chemical reactions
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products. An arrow is drawn between the reactants and products to indicate the direction of the chemical reaction, though a chemical reaction is not always a "one-way street," as we'll explore further in the next section.
For example, the reaction for breakdown of hydrogen peroxide (\text{H}_{2}H

start text, H, end text, start subscript, 2, end subscript\text{O}_{2}O

start text, O, end text, start subscript, 2, end subscript) into water and oxygen can be written as:
2 \text{H}_{2}2H

2, start text, H, end text, start subscript, 2, end subscript\text{O}_{2} \text{(hydrogen peroxide)}O

(hydrogen peroxide)start text, O, end text, start subscript, 2, end subscript, start text, left parenthesis, h, y, d, r, o, g, e, n, space, p, e, r, o, x, i, d, e, right parenthesis, end text \rightarrow→right arrow 2\text{H}_{2}\text O \text{(water)}2H

O(water)2, start text, H, end text, start subscript, 2, end subscript, start text, O, end text, start text, left parenthesis, w, a, t, e, r, right parenthesis, end text + \text{O}_{2}\text{(oxygen)}O
