Free energy is a thermodynamic function that is the most useful criterion for predicting the direction of a chemical reaction and the composition of the system at equilibrium. Free energy is also known as Gibbs function and is denoted by G.Gibbss function is the capacity ..

Here in this page we are going to discuss about free energy change at equilibrium. An irreversible process or equilibrium is one where the system or its surroundings cannot be restored back to their initial state after a thermodynamic change has taken pla..

Free energy of a system is defined as the maximum amount of energy available to a system during a process that can be converted into useful work. In other words it is a measure of capacity of a system to do useful work. It is denoted by symbol G and is given ..

First law of thermodynamics say that there is a conservation of energy in a chemical reaction. Work is done by the system or on the system to the extent of energy evolved or absorbed. The first law however fails to explain the following. a) It imposes no restriction on the direction of flo..

The Gibbs free energy is a potential of thermodynamics that is used to measure the "useful" or process-initiating work obtained from thermodynamic states as isothermal, isobaric. In mechanics, potential energy is the capacity to do work. Similarly, there are different potentials which..

Here in this page we are going to discuss about Gibbs free energy of mixing. Mixing is combining of different components without any chemical change taking place. The mixing can occur between two or more components present in same or different states and results in an increase in volume f..

The standard free energy change is defined as the free energy change for a process at 298 K and 1 atmospheric pressure in which the reactants in their standard states are converted to the products in their standard states. Like the standard enthalpy of formation of an element, ..

Here in this page we are going to learn about the brief of concepts like enthalpy , enthopy, free energy and temperature. Some chemical reactions occur spontaneously. These cannot be reversed once they occur. Other reactions do not reach completion but remain in a dynamic equilibrium wher..
