Sir/madam please explain me about reduction and oxidation and also explain briefly about the rate of chemical reaction and the factors influencing rate of chemical reaction
1) oxidation is the gain of oxygen or loss of hydrogen.in the case of ions an element lose electrons in a chemical reaction and carry positive charge.
2) reduction is the loss of oxgen or gain of hydrogen .in case of ions element gain electrons in a chemical reaction and carry negative charge.
3) The rate of chemical reaction defined as the change in concentration of a reaction or product in unit time.It can be expressed in terms of:-
1-the rate of decrease in concentration of any one of the reactants,
2-the rate of increase in concentration of any of the products.
4)Factors affecting rate of chemical reaction are:
1) Concentration of the reacting species.
2) Temperature of the system.
3) Nature of the reactant and products.
4) Presence of catalyst.
5) Surface area.
6) Exposure to radiations.
