Solution

The correct option is D $d e c r e a s i n g [T l^{+}]$
The cell reaction is:
$T l_{(s)} + C u_{a q}^{2 +} ⇌ T l_{a q}^{+} + C u_{(s)}$
$Q_{c} = \frac{T l^{+}}{C u^{2 +}}$
$E = E^{0} - \frac{0.0591}{n} l o g Q_{c} a t 298 k$
$E = E^{0} - \frac{0.059}{n} l o g (\frac{[T l^{+}]}{[C u^{2 +}]})$
