Identify the INCORRECT statement
- A A process will always be spontaneous at all temperatures, if T\(\Delta\)S is positive
- B For spontaneous process \(([\Delta H_{system} - T\Delta S_{system}]) < 0\)
- C At 273K, for the transition Ice\((s) \longrightarrow\) Water \((l)\), \(\Delta\)G = 0
- D Entropy is an extensive property and state function
Answer & Solution
Correct Answer
(A) A process will always be spontaneous at all temperatures, if T\(\Delta\)S is positive
Step-by-step Solution
Detailed explanation
\(\Delta G = \Delta H - T\Delta S\) For a process to be spontaneous at all temperatures, \(\Delta G\) must be negative at all temperatures. This is possible only when \(\Delta H 0\). If \(\Delta S > 0\) (meaning \(T\Delta S\) is positive) but \(\Delta H > 0\), the process will…
