$K_1 = 1.6 \times 10^3$ and
$[Ag(NH_3)]^+ + NH_3 \rightleftharpoons [Ag(NH_3)_2]^+$ ;
$K_2 = 6.8 \times 10^3$ .
Then formation constant of $[Ag(NH_3)_2]^+$ is :
$PhC{{O}_{2}}H\xrightarrow[2.\,N{{H}_{3}}]{1.\,PC{{l}_{5}}}A\xrightarrow[2.\,{{H}_{2}}/Ni]{1.\,{{P}_{4}}{{O}_{10}}.heat}B.$ The final product $(B)$ is
