A) \[2.76\,J{{K}^{-1}}\]
B) \[2.12\,J{{K}^{-1}}\]
C) \[1.12\,J{{K}^{-1}}\]
D) \[1.40\,J{{K}^{-1}}\]
Correct Answer: A
Solution :
Standard entropy of formation of \[C{{O}_{2}}(g)\]= standard entropy of \[C{{O}_{2}}(g)-\][Standard entropy of \[C(s)-\]standard entropy of \[{{O}_{2}}(g)\]] \[=213.5\,-[5.740+205]\]\[=2.76\,J/K\].
