Assertion $(A)$ : Vinyl halides do not undergo nucleophilic substitution easily.
Reason $(R)$ : Even though the intermediate carbocation is stabilized by loosely held $p-$ electrons, the cleavage is difficult because of strong bonding.
For the cell $\mathrm{Cu}(\mathrm{s})\left|\mathrm{Cu}^{2+}(\mathrm{aq})(0.01 \mathrm{M}) \| \mathrm{Ag}^{+}(\mathrm{aq})(0.001 \mathrm{M})\right| \mathrm{Ag}(\mathrm{s})$ the cell potential $=.....\times 10^{-2} \mathrm{~V}$
