At 373 K, the heat of transition for `H_(2)O(l) rarr H_(2)O_((g))" is "Delta H =37.3 kJ mol^(-1)` The entropy change corresponding to the reaction is

Options

A. `111.9 mol^(-1) K^(-1)`
B. `37.3 J mol^(-1) K^(-1)`
C. `100 J mol^(-1) K^(-1)`
D. `74.6 J mol^(-1) K^(-1)`

Answer

C

Explanation

`Delta S =(37.3)/(373) xx1000=100 J mol^(-1) K^(-1)`
