Equilibria in Physical Processes
Equilibrium represents the state of a process in which the properties like temperature, pressure, concentration of the system do not show any change with the passage of time. If the opposing processes involve only physical changes, the equilibrium is called physical equilibrium. If the opposing processes involve chemical changes i.e. the opposing processes are chemical … [Read more...] about Equilibria in Physical Processes
