A) 910 K
B) 1110 K
C) 510 K
D) 710 K
Correct Answer: B
Solution :
\[\Delta G=\Delta H\,\,-\,T\Delta S\] At equilibrium, \[\Delta G = 0\] \[=\,\,0=(170\times {{10}^{3}}\,J)-\,\,7(170J{{K}^{-1}})\] \[\Rightarrow \,\,\,T=1000K\] For spontaneity, \[\Delta G\] is - ve, which is possible only if \[\operatorname{T}>1000\,\,K.\]You need to login to perform this action.
