A) 2.0968 V
B) 1.0968 V
C) 0.0968 V
D) 1.968 V
Correct Answer: B
Solution :
\[{{C}_{5}}{{H}_{12}}+8{{O}_{2}}\xrightarrow{{}}5C{{O}_{2}}+6{{H}_{2}}O\] \[\Delta {{G}^{o}}=5\times {{G}^{o}}C{{O}_{2}}+6\times {{G}^{o}}{{H}_{2}}O-G_{{{C}_{5}}{{H}_{12}}}^{o}-8\times G_{{{O}_{2}}}^{o}\] \[=5\times (-394.4)+6\times (-237.2)+8.2\] \[=-3387\,kJ\] \[\Delta {{G}^{o}}=nF{{E}^{o}}\] \[-3387\times {{10}^{3}}=32\times {{E}^{o}}\times 96500\] \[[{{({{C}^{-2.4}})}_{5}}\xrightarrow{{}}5({{C}^{4+}})+32e]\] \[\therefore \]\[{{E}^{o}}=1.0968\,V;n=32\]You need to login to perform this action.
