The rate of reaction may be determined using the concentration-time graph of either a reactant or product. The slope of the graph helps in determining the rate of reaction. If the rate of reaction increases, the magnitude of the slope of the graph will increase. This indicates that more reactant is being consumed per unit time, or, in the case of the product, more product is being produced per unit time.
The isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions because the nuclear reactions involve changes to protons and neutrons in an atom and isotopes differ in neutrons and so they react differently to nuclear changes. While for chemical reactions, the electrons in an atom are involved but the isotopes do not differ in electrons and so they react the same way during chemical changes.
Answer: Option A & C
<u>Explanation:</u>
The reactants of chemical and nuclear reactions are different. The reactants of chemical reactions are the electrons present in the outermost shell of the reactants, while the reactants of nuclear reactions are either the nuclei of reactants or a nuclei and any subatomic particles of other reactants.
Thus it can be understood that chemical reactions consider the electrons while nuclear reactions consider the nuclei or the number of protons and neutrons of the reactants.
The isotopes of elements contain different mass number or we can say different number of neutrons but the number of electrons are same, so they behave differently in nuclear reactions and similar in chemical reactions.
Electrical energy is the energy of electrons
