The difference between the calculated voltage (based on standard potentials) and the actual voltage required to cause electrolysis is called overvoltage.
<h3>Electrolysis </h3>
Electrolysis is the technique of causing a chemical change in a substance by passing an electric current through it. The substance either loses or gets an electron during the chemical transition (oxidation or reduction). The procedure is carried out in an electrolytic cell, a device made up of positive and negative electrodes that are kept apart and submerged in a solution with ions that are both positively and negatively charged. The chemical that needs to be converted might either be dissolved in the solution or could form the electrode. The negatively charged electrode (cathode) receives electrical current (i.e., electrons), which travels there and combines with the components of the solution to convert them (reduced).

Answer:
The correct answer is option b, that is, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
Explanation:
The carbon-14 atoms, which are created by the cosmic rays associates with oxygen to produce carbon dioxide that plants captivate naturally and comprise it into plant fibers by the process of photosynthesis. Afterward, the plants are consumed by animals and human beings, thus, they take in carbon-14 as well.
The ratio of usual carbon-12 to carbon-14 in the air and in all the living species at a particular period is almost the same. These radioactive isotopes react in a similar manner as stable isotopes in the chemical reactions in the body.
Answer:
The correct option is;
The reaction pathway for the trials is different
Explanation:
The effect of a catalyst in a chemical reaction is to increase the rate of a reaction by changing the pathway or mechanism of the reaction and/or to lower the transition state's energy thereby lowering the activation energy of the reaction
The pathway of the reaction is changed by the catalyst by the formation of intermediate compounds by the catalyst which require lower activation energy to form the products than the original non-catalyzed reactants. In the process the catalyst is regenerated, thereby, not taking part in the reaction.
