Question

The reaction $C{u}^{2+}\left(eq\right)+2C{l}^{\ominus }\left(aq\right)\to Cu\left(s\right)+C{l}_2\left(g\right)$ has $E_{cell}^{\ominus }=-1.03V$. This reaction:

• A. can be made to produce electricity in voltaic cell
• B. can be made to occur in an electrolytic cell
• C. can occur in acidic medium only
• D. can occur in basic medium only

Answer 1

Answer: (B)

can be made to occur in an electrolytic cell

$C{u}^{2+}+2C{l}^{\ominus }\to Cu+C{l}_2;E_{cell}^{\ominus }<0$

$\Rightarrow$ Reactions which have $E_{cell}^{\ominus }<0$ ( non-spontaneous) can be made to occur in an electrolytic cell.
