A large Kc indicates large concentrations of products at equilibrium as follows: Kc > 1000 means that the reaction goes to completion. A small Kc…

Every reversible system has its own position of equilibrium under any given set of conditions. For any given reversible reaction at equilibrium, the ratio of…

The Haber’s process for producing ammonia from N2 and H2 is an important industrial example of a reaction that does not go to completion. It…

When substances react in a closed system, they eventually form a mixture of the constant composition of products and unreacted reactants, in a dynamic chemical…

A reversible reaction is a chemical reaction that results in an equilibrium mixture of reactants and products. If steam is passed over the hot iron,…

In the electrolysis of copper chloride, what mass of copper would be produced by a current of 1000 A running for 1 hour? First it…

Michael Faraday found that the mass of substances released at the electrodes is directly related to the total charge that has passed through the electrical…

A Downs cell is a commercial electro- chemical cell used to obtain sodium metal by electrolysis of molten NaCI. A number of other reactive metals…

An electrolytic cell is an electro-chemical cell in which an electric current drives an otherwise non-spontaneous reaction. Note that the electrolytic cell requires an external…

A fuel cell is a device that generates electricity by a chemical reaction. A proton-conducting polymer membrane (the electrolyte) separates both the anode and cathode…
