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