A) 1500 and 3500 K
B) 3000 and 3500 K
C) 1000, 1500 and 3000 K
D) 1500, 3000 and 3500 K
E) At all these temperatures
Correct Answer: C
Solution :
\[\because \] \[\Delta G=\Delta H-T.\Delta S\] For a spontaneous reaction\[\Delta G\]should be negative \[\Delta H=-238\text{ }kJ,\Delta S=-\text{ }87\text{ }J{{K}^{-1}}\] Hence, reaction will be spontaneous when \[\Delta H>T.\Delta S\]. Therefore, at 1000, 1500 and 3000 K the reaction would be spontaneous.You need to login to perform this action.
