Question

For the given cell reaction :
$C{u}^{2+}\left(aq\right)+2C{l}^{-}\left(aq\right)\to Cu\left(s\right)+C{l}_2\left(g\right)$
$E_{cell}^{\circ }$ is given as $-1.02V$.
Which of the following is correct?

• A. The given reaction is spontaneous
• B. Reaction will occur whenever $C{u}^{2+}$and $C{l}^{-}$ are brought together in an aqueous solution.
• C. The given reaction is non-spontaneous
• D. The reaction is in equilibrium

Answer 1

The correct option is C The given reaction is non-spontaneous

For a given reaction to be spontaneous,$E_{cell}^{\circ }>0$

For the reaction , since $E_{cell}^{\circ }$ has a negative value ,

So, the given reaction is a non-spontaneous redox reaction
