A) \[1.0\times {{10}^{1}}\]
B) \[1.0\times {{10}^{5}}\]
C) \[1.0\times {{10}^{10}}\]
D) \[1.0\times {{10}^{30}}\]
Correct Answer: C
Solution :
\[E{{{}^\circ }_{cell}}=\frac{2.303RT}{nF}\times \log {{K}_{eq}}\] \[E{{{}^\circ }_{cell}}=\frac{0.0591}{n}\log {{K}_{eq}}\] \[(At\,\,298\,\,K)\] \[0.591=\frac{0.0591}{1}\log {{K}_{eq}}\] \[\therefore \] \[\log {{K}_{eq}}=10\] \[\therefore \] \[{{K}_{eq}}=1\times {{10}^{10}}\]
