Unit of entropy is:

  • Correct answer
    A
    $\mathrm{JK}^{-1} \mathrm{~mol}^{-1}$
  • B
    $\mathrm{J} \mathrm{mol}^{-1}$
  • C
    $\mathrm{J}^{-1} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$
  • D
    $\mathrm{JK} \mathrm{mol}^{-1}$

Solution

Entropy is a function of the state of a thermodynamic system. It is extensive quantity, (SI unit: joule/K/ $\mathrm{mol})$.

Hence, the correct answer is option: 'A'.
