Question

What are the similarities between chemical reaction and nuclear reaction?

Answer 1

Answer:

· Nuclear reactions involve a change in an atom's nucleus, usually producing a different element ,along with the emission of radiations Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. So nuclear reaction is nuclear phenomenon and chemical reaction is extra-nuclear phenomenon.

· Different isotopes of an element normally behave similarly in chemical reactions as their extra-nuclear electronic configurations are same. The nuclear chemistry of different isotopes vary greatly from each other.

· Rates of chemical reactions are influenced by external effect like temperature,pressure and catalysts. Rates of nuclear reactions are spontaneous and are unaffected by such factors.

· Nuclear reactions are independent of the chemical form of the element.This means both in elemental and in compound state same amount of radio-element shows similar radioactivity.

· Energy changes accompanying nuclear reactions are much larger. This energy comes from destruction of mass.

· In a nuclear reaction, mass is not strictly conserved. Some of the mass is converted into energy,according to the equation E = mc2 and the order of energy evolved during a nuclear reaction is much higher than that of a chemical reaction.

Explanation:

Answer 2

There are similarities and differences between chemical reaction.

• In both reactions reactants combines to give a product.
• Nuclear reaction involves a change in the nucleus of the element, in chemical reactions there is a rearrangement in the electrons.
• Isotopes behaves similarly in chemical reactions as their electron arrangements are the same, but their nuclear reactions are notably different because of difference in arrangement of neutrons.
• Rate of chemical reaction can be influenced by a number of external factors like pressure, temperature, catalyst, etc.
• But nuclear reactions are spontaneous and external factors have no influence on it.
• More energy is released in nuclear reactions.
• Energy is not conserved in nuclear reactions.
