THermodynamic free enrgy is the amount of work a thermodynamic system can perform. The concept is useful in the thermodynamics of chemical or thermal processes in engineering and science. The free energy is the internal energy of a system minus the amount of energy that cannot be used to perform work. This unusable energy is given by the entropy of a system multiplied by the temperature of the system.Like the internal energy, the free energy is a thermodynamic state function.
Definitions Oxidation exactly meant 'combination with oxygen' and reduction 'removal of oxygen'. These definitions have been illustrated. Oxidation implies combination with a
The value of the energy for the first excited state of hydrogen atom will be: (1) - 13.6 ev (2)- 3.40 eV (3) -1.51eV
Glucose and fructose are epimers so they are differ in their second carbon position and remaining is same so when they react with phenylhydrazeen they give same osazone
