Chemistry

Assume a cell with the following reaction

C{u_{(s)}} + 2A{g^ + }(1 \times {10^{ - 3}}M) \to C{u^{2 + }}(0.250M) + 2A{g_{(s)}}

E_{cell}^\Theta = 2.97

V
E_cell for the above reaction is ______________ V. (Nearest integer)
[Given : log 2.5 = 0.3979, T = 298 K]

$E = {E^o} - {{0.059} \over 2}\log {{[C{u^{ + 2}}]} \over {{{[A{g^ + }]}^2}}}\\$

$= 2.97 - {{0.059} \over 2}\log {{0.25} \over {{{({{10}^{ - 3}})}^2}}} = 2.81V$
