Difference between Electrochemical and Electrolytic cell

July 19, 2018 by Dr. IM Leave a Comment

What are the difference between Electrochemical and Electrolytic cell? Answer: Electrochemical cell It converts chemical energy (of a redox reaction) into electrical energy. At the electrodes, spontaneous redox reaction takes place. The electrodes are made of dissimilar metals. Each electrode is dipped in electrolytic solution of its own ions. Salt bridge is … [Read more...] about Difference between Electrochemical and Electrolytic cell

Phase diagram for Water System

What is the Phase diagram for water system? What is the Gibbs phase rule? Answer: The water system : Under normal conditions the water system is a three phase and one component system. The three phases are liquid, ice and vapour. All these are represented by one chemical entity (H2O), hence it is one component system. Phase diagram for water system The three forms of … [Read more...] about Phase diagram for Water System

Bonding Molecular Orbitals | Antibonding Molecular Orbitals (AMO and BMO)

July 19, 2018 by Dr. IM Leave a Comment

What are the difference between Bonding Molecular Orbitals and Antibonding Molecular Orbitals? Answer: Bonding molecular orbitals (BMO) They are formed by the additive effect of the atomic orbitals. fb = y1 + y2 . The electron density increases in the region between the nuclei of bonded atoms. The electrons present in the bonding orbitals result in an attraction … [Read more...] about Bonding Molecular Orbitals | Antibonding Molecular Orbitals (AMO and BMO)
