Which of the following compounds will form the precipitate with aq. ${\mathrm{A}\mathrm{g}\mathrm{N}\mathrm{O}}_3$  solution most readily?

If the equilibrium constant for $A\rightleftharpoons B+C$ is $K_{\left(\text{eq}\right)}^{\left(1\right)}$ and that of $B+C\rightleftharpoons P$ is $K_{\left(\text{eq}\right)}^{\left(2\right)}$ , the equilibrium constant for $\mathrm{A}\rightleftharpoons \mathrm{P}$  is:

The process that is NOT endothermic in nature is:

Among the following compounds, which one has the shortest $\mathrm{C}-\mathrm{C}\mathrm{l}$  bond?

$250\mathrm{m}\mathrm{L}$ of a waste solution obtained from the workshop of a goldsmith contains $0.1\mathrm{M}$ ${\mathrm{A}\mathrm{g}\mathrm{N}\mathrm{O}}_3$ and $0.1\mathrm{M}\mathrm{A}\mathrm{u}\mathrm{C}\mathrm{l}$ . The solution was electrolyzed at $2\mathrm{V}$ by passing a current of $1\mathrm{A}$ for 15 minutes. The metal/metals electrodeposited will be : $\left({\mathrm{E}}_{{\mathrm{A}\mathrm{g}}^{+}/\mathrm{A}\mathrm{g}}^{\mathrm{o}}=0.8\mathrm{V},{\mathrm{E}}_{{\mathrm{A}\mathrm{u}}^{+}/\mathrm{A}\mathrm{u}}^{\mathrm{o}}=1.69\mathrm{V}\right)$
