Zn + Cu2+(aq) ⇋ Cu + Zn2+(aq)
Reaction quotient is Q =
. Variation of Ecell with log Q is of the type with OA = 1.10 V. Ecell will be 1.1591 V when
Reaction quotient is Q =
. Variation of Ecell with log Q is of the type with OA = 1.10 V. Ecell will be 1.1591 V whenOptions
A.[Cu2+] / [Zn2+] = 0.01
B.[Zn2+] / [Cu2+] = 0.01
C.[Zn2+] / [Cu2+] = 0.1
D.[Zn2+] / [Cu2+] = 1
Solution
Ecell = E-cell - 
log
From line OA = E-cell = 1.10 V
= 10-2 M, then Ecell = 1.1591 V
logFrom line OA = E-cell = 1.10 V
= 10-2 M, then Ecell = 1.1591 VCreate a free account to view solution
