Write general characteristics of equilibria involving physical processes. |
|
Answer» Solution :For the physical processes FOLLOWING characte ristics are COMMON to the system at EQUILIBRIUM. (i) Equilibrium is possible only in a closed system at a given temperature. (ii) Both the OPPOSING processes occur at the same rate and there is a dynamic but stable condition. (iii) All measurable properties of the system remain constant. (iv) When equilibrium is attained for a physical process, it is characterised by constant value of one of its PARAMETERS at a given temperature. (v) The magnitude of such quantities at any stage indicates the extent to which the physical process has proceeded before reaching equilibrium. |
