A) \[-89.0\,kJ\]
B) \[-89.0\,J\]
C) \[-44.5\,kJ\]
D) \[-98.0\,kJ\]
Correct Answer: A
Solution :
[a] \[Cu+2A{{g}^{+}}(aq)\xrightarrow{{}}C{{u}^{2+}}(aq)+2Ag(s)\] Here \[n=2,E_{cell}^{{}^\circ }=+0.46V\] \[\Delta G{}^\circ =-nE{}^\circ F\] \[=\frac{-2\times 0.46\times 96500}{1000}kJ\simeq -89kJ\]You need to login to perform this action.
