Question

State True or False.

At equilibrium state ${\Delta }_{total}S=0$

• A. True
• B. False

Answer 1

The correct option is A True

$\Rightarrow$ Entropy change in spontaneous process:

$\Delta S_{System}+\Delta Ssurrounding\ge O$

The sign $>$ is for spontaneous process .A state of equilibrium in a close system is attained spontaneously. As system approaches equilibrium from non- equlibrium state-$S_{total}$ keeps on increasing and at equilibrium $S_{total}$ attains its maximum value.

$\Rightarrow$ ${\Delta }_{Total}S=0atequilibrium$

at this point ${\Delta }_{Total}S$=Maximum value at equilibrium in a close system
