Concept Introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
A chemical reaction in which oxidation process and reduction process take place simultaneously is called a
An oxidizing agent is a substance that has the capacity to oxidize other substances and get reduced in a chemical reaction.
A reducing agent is a substance that has the capacity to reduce other substances and get oxidized in a chemical reaction.
The hydrogen-oxygen fuel cell is a device that generates electricity by the chemical reaction between a source fuel and an oxidant.
In a fuel cell, the chemical energy is directly converted into electricity by the oxidation of methane.
In conventional power plants where methane is used as a fuel, the electricity is generated by the oxidation of methane.
The three steps involved in the production of electricity are as:
The molten carbonate fuel cells use potassium carbonate as an electron transfer medium and methane is used as a fuel.
The total hours of operation are calculated as.

- Give a thermodynamic argument for why it is more efficient to generate electricity from methane oxidation in a fuel cell rather than from methane oxidation in a conventional combustion power plant.arrow_forwardZinc is produced by electrolytic refining. The electrolytic process, which is similar to that for copper, can be represented by the two half-reactions Zn(impure,s)Zn2++2eZn2++2eZn(pure,s) For this process, a voltage of 3.0 V is used. How many kilowatt hours are needed to produce one metric ton of pure zinc?arrow_forwardIf a barrel plating run uses 200.0 A for exactly 6 hours for an electroplating application at 0.30 V, how many kilowatt-hours have been used in the run? If the voltage is 0.90 V, what is the power usage (in kWh)?arrow_forward
