Q1: Electrode potential is not concerned with the measurment of

ANS:B - temperature

Electrode potential refers to the voltage or electrical potential difference between an electrode and its surrounding solution in an electrochemical system. It is a fundamental property in electrochemistry and is primarily influenced by the redox reactions occurring at the electrode-solution interface. Temperature does not directly affect the electrode potential. The electrode potential is primarily determined by the nature of the electrode material, the species involved in the electrochemical reaction, and the concentrations of these species in the solution. However, temperature indirectly influences electrode potential through its effects on reaction rates and equilibrium constants. According to the Arrhenius equation, the rate of electrochemical reactions generally increases with temperature due to the higher kinetic energy of molecules, leading to faster electron transfer kinetics. Additionally, temperature affects the equilibrium constants of the redox reactions involved, altering the distribution of chemical species at the electrode interface and thus influencing the electrode potential. In summary, while temperature does not directly measure or affect electrode potential, it can influence the kinetics and thermodynamics of the redox reactions occurring at the electrode, thereby indirectly impacting the electrode potential in an electrochemical system.
