Choose the correct answer from the options given below:
$2NOCl(g)\, \rightleftharpoons \,2NO(g)\, + \,C{l_2}(g)$
[Given : $K_P = 8 \times10^{12}\,atm$ at $500\,K$ use $R = 0.08\,L\,atm\,mol^{-1}\,K^{-1}$ ]
$Cu ( s )+2 Ag ^{+}( aq ) \rightleftharpoons Cu ^{2+}( aq )+2 Ag ( s )$
The equilibrium constant for the reaction.$\frac{1}{2} Cu ^{2+}( aq )+ Ag ( s ) \rightleftharpoons \frac{1}{2} Cu ( s )+ Ag ^{+}( aq )$ is $x \times 10^{-8}$. The value of $x$ is (Nearest Integer)
$R - C \equiv C - R\xrightarrow{{Pd/BaS{O_4}}}A$
$R - C \equiv C - R\xrightarrow{{Na/Liq.\,NH_3}}B$
