A)
\[\Delta H\] is \[+ve;\] \[\Delta S\] is also \[+ve\]
B)
\[\Delta H\] is \[-ve;\] \[\Delta S\] is also \[-ve\]
C)
\[\Delta H\] is \[-ve;\] \[\Delta S\] is \[+ve\]
D)
\[\Delta H\] is \[+ve;\] \[\Delta S\] is \[-ve\]
Correct Answer: D
Solution :
When \[\Delta G\] is \[+ve\] then reaction is not possible. \[\Delta G=\Delta H-T.\Delta S\] If \[\Delta H=+ve\] and \[\Delta S=+ve\]then \[\Delta G=+ve\]only when \[\Delta H>T.\Delta S\]and if \[\Delta H=+ve\] and \[\Delta S=-ve\] then \[\Delta G=+ve\]You need to login to perform this action.
