The equivalent volume of ${\mathrm{CO}}_2$ in the following reaction is:

$2{\mathrm{NaHCO}}_3\to {\mathrm{Na}}_2{\mathrm{CO}}_3+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CO}}_2$

The equivalent volume of ${\mathrm{CO}}_2$ in the following reaction is:

${\mathrm{NaHCO}}_3+\mathrm{HCl}\to \mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CO}}_2$

The figure shows the effect of pressure on the compressibility factor, $\mathrm{Z}$, of a gas.

The wrong conclusion (s) is (are):

Equivalent weights of ${\mathrm{CO}}_2$ in the following reactions:

$2{\mathrm{NaHCO}}_3={\mathrm{Na}}_2{\mathrm{CO}}_3+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CO}}_2$ and

${\mathrm{NaHCO}}_3+\mathrm{HCl}=\mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CO}}_2$, are respectively:
