If the enthalpy change for the transition of liquid water to steam is 30 kJ mol−130\ \text{kJ mol}^{-1} at 27∘C27^\circ C, the entropy change for the process would be

Multiple Choice Options

  • A 10 J mol−1 K−110\ \text{J mol}^{-1}\ \text{K}^{-1}
  • B 1.0 J mol−1 K−11.0\ \text{J mol}^{-1}\ \text{K}^{-1}
  • C 0.1 J mol−1 K−10.1\ \text{J mol}^{-1}\ \text{K}^{-1}
  • D 100 J mol−1 K−1100\ \text{J mol}^{-1}\ \text{K}^{-1}
