: E=Ecello+(0.0591/2) log ([Ag(aq)+]2/[Co(aq)2+])

Q. Which of the following will form a cell with the highest voltage?

$1 M A g^{+}, 1 M C o^{2 +}$

$2 M A g^{+}, 2 M C o^{2 +}$

$0.1 M A g^{+}, 2 M C o^{2 +}$

$2 M A g^{+}, 0.1 M C o^{2 +}$

: $E = E_{ce ll}^{o} + \frac{0.0591}{2} lo g \frac{[ A g _{(a q)}^{+} ] ^{2}}{[ C o _{(a q)}^{2 +} ]}$
