Chapter 20, Problem 1QP

Interpretation Introduction

Interpretation:

The difference between nuclear reactions and ordinary chemical reactions are to be explained.

Concept introduction:

The reactions in which a nucleus or two nuclei of an atom and nucleons from the outer side of the atom collide with each other to form nuclidesthatturn out to be different from the starting nuclides are called nuclear reaction.

An ordinary chemical reaction is a reaction in which a substance’s identity is changed. In these kinds of reactions, one or more substances are convertedinto different substances.

Answer to Problem 1QP

Solution: Nuclear reactions involve elements that are converted into isotopes. They also involve neutrons, electrons and protons. Absorption is involved in theses reactions. Catalyst, pressure and temperature cannot affect the rate of such reactions.

Ordinary reactions involve the breaking and formation of bonds due to which atoms are rearranged. These reactions involve atoms in their molecular or atomic orbitals. Catalyst, pressure and temperature affect the rate of these reactions.

Explanation of Solution

The reactions in which a nucleus or two nuclei of an atom and nucleons from the outer side of the atom collide with each other to form nuclidesthatcome out to be different from the starting nuclides are called nuclear reactions. These reactions involve the elements that are converted into other isotopes. They also involve neutrons, electrons and protons. Absorption is involved in these reactions as these reactions release a huge amount of energy. Catalyst, pressure and temperature cannot affect the rate of these reactions.

An ordinary chemical reaction is a reaction in which a substance’s identity is changed. Ordinary reactions involve the breaking and formation of bonds due to which atoms are rearranged. These reactions involve atoms in their molecular or atomic orbitals. These reactions lead to absorption as they release a small amount of energy. Catalyst, pressure and temperature affect the rate of these reactions.

Hence, nuclear reactions are different from ordinary chemical reactions.

Conclusion

The properties of the nuclear reactions are different from the ordinary chemical reactions, which shows that nuclear reactions and ordinary chemical reactions are different from each other.
