For the following process \[ \mathrm{H}_2 \mathrm{O}(l)(1 \text { bar, } 373.15 \mathrm{~K}) \rightleftharpoons \mathrm{H}_2 \mathrm{O}(g) \] ( \(1 \mathrm{bar}, 373.15 \mathrm{~K}\) ) identify the correct set of thermodynamic parameters.
- A \(\Delta G=0, \Delta S=+v e\)
- B \(\Delta G=0, \Delta S=-v e\)
- C \(\Delta G=+v e, \Delta S=0\)
- D \(\Delta G=-v e, \Delta S=+v e\)
Answer & Solution
Correct Answer
(A) \(\Delta G=0, \Delta S=+v e\)
Step-by-step Solution
Detailed explanation
State changes from liquid to gaseous thus movement of particles increases and hence, entropy change is positive. There is no change in pressure and temperature so change in \(G\) is zero.
