Question

Which graph correctly correlates $E_{\text{Cell }}$ as a function of concentration for the cell (for different values of M and M')?
$Zn(s)+C{u}^{2+}(M)\to Z{n}^{2+}\left(M^{\prime }\right)+Cu(s)$
$E_{cell}^{\circ }=1.10V$
$X$ -axis $:\log 10\frac{\left[Z{n}^{2+}\right]}{\left[C{u}^{2+}\right]},Y$ -axis : Ecell

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

$E_{cell}=1.10-(0.0591/2)\log \left[C{u}^{2+}\right]/\left[Z{n}^{2+}\right]$

$y=c+(-m)x$

This increase in $\left[Z{n}^{2+}\right]$ will increase slope in -ve side.
