$2N_2O_5 \rightarrow 4NO_2 + O_2$ can be written in three ways.

$\frac{-d[N_2O_5 ]}{dt} = k[N_2O_5]$

$\frac{d[NO_2 ]}{dt} = k'[N_2O_5]\,;$   $\frac{d[O_2 ]}{dt} = k"[N_2O_5]$

The relationship between $k$ and $k'$ and betweenk and $k''$ are

$CoCl _{3} . xNH _{3}+ AgNO _{3}( aq ) \rightarrow$

If two equivalents of $AgCl$ precipitate out, then the value of $x$ will be $....$
