Kindly consider the following figure

The compressibility factor of a Vanderwaal gas is 0.5 at $27°C$  and 24 atm. The value of Vanderwaal constant 'a' (in atm-L²/mol²) is (b = 0.10 L/mol, R = 0.08 L-atm/K-mol)

Consider the following reactions of 1A metals.

M + $\left(x+y\right)N{H}_3$ $\stackrel{}{\to }{\left[M{\left(N{H}_3\right)}_x\right]}^{+}+{\left[e{\left(N{H}_3\right)}_y\right]}^{-}$  

$M_{\left(am\right)}^{+}+e^{-}+N{H}_3\left(\mathcal{l}\right)\stackrel{}{\to }MN{H}_{2\left(am\right)}+\frac{1}{2}{H}_2\left(g\right)$
