How do you find the feasibility of a redox reaction?
A redox reaction is feasible only if the species which has higher potential is reduced i.e., accepts the electrons and the species which has lower reduction potential is oxidized i.e., loses electrons. Therefore, silver will be reduced and copper will be oxidized and the above reaction is not feasible.
How do you find the feasibility of a reaction in electrochemistry?
The feasibility of a redox reaction can be predicted with the help of the electrochemical series. E∘cell=+ve, the reaction is feasible. E∘cell= -ve, the reaction is not feasible.
How cell potential is used to measure the feasibility of a reaction?
Standard electrode potentials are widely used to predict the feasibility of redox processes. In general if the electrode potential for the reaction is positive, it is regarded as being feasible. The value of Eo is related to the equilibrium constant for the reaction.
How do you introduce a redox reaction?
Redox reactions, as they are called, are the energy‐producing reactions in industry as well as in the body. The core of a redox reaction is the passing of one or more electrons from one species to another. The species that loses electrons is said to be oxidized, and the species gaining electrons is reduced.
What do you mean by feasible?
1 : capable of being done or carried out a feasible plan. 2 : capable of being used or dealt with successfully : suitable. 3 : reasonable, likely gave an explanation that seemed feasible enough.
How does it help in predicting whether a particular redox reaction is feasible in a given direction or not?
As per the electrochemical series, a component with a higher decrease potential can oxidize another so if emf is positive then the reaction will be feasible at that temperature. Consequently, the feasibility of the reaction can be understood with the help of electrochemical series.
What occurs during a redox reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
What is feasibility of reaction?
For a reaction to be feasible at a given temperature, it must happen spontaneously, which means no extra energy needs to be put in for the reaction to occur. To find out whether a reaction is feasible, you can calculate the Gibbs free energy change (ΔG) for that particular reaction.
