Chemical Thermodynamics Question 332

Question: For the process $ H_2O(I)\to H_2O(g) $ At $ T=100{}^\circ C $ and 1 atmosphere pressure, the correct choice is

Options:

A) $ \Delta S_{system}>0,and,\Delta S_{surroundings}>0 $

B) $ \Delta S_{system}>0,and,\Delta S_{surroundings}<0 $

C) $ \Delta S_{system}<0,and,\Delta S_{surroundings}>0 $

D) $ \Delta S_{system}<0,and,\Delta S_{surroundings}<0 $

Show Answer

Answer:

Correct Answer: B

Solution:

  • Given conditions are boiling conditions for water due to which $ \Delta S_{total}=0 $

$ \Delta S_{system}+\Delta S_{surrounding}=0 $

$ \Delta S_{system}=-\Delta S_{surrounding} $ for process, $ \Delta S_{system}>0\Rightarrow \Delta S_{surrounding}<0 $
