A) 2040.5 K
B) 1890.0 K
C) 2480.3 K
D) 2380.5 K
Correct Answer: C
Solution :
\[\Delta {{G}^{o}}=\Delta {{H}^{o}}-T\Delta {{S}^{o}}\] For a reaction to be spontaneous \[\Delta {{G}^{o}}\]must be negative i.e., \[T\Delta {{S}^{o}}>\Delta {{H}^{o}}\] \[T>\frac{\Delta {{H}^{o}}}{\Delta {{S}^{o}}}\Rightarrow T>\frac{491.1\times 1000}{198}\] \[T>2480.3K\]You need to login to perform this action.
