$Pt|Cl_2| Cl^-(1\,M) ||Cl^-(1\,M)|Cl_2|Pt$

$P_1\, atm$                               $P_2\, atm$

$A$. $\mathrm{Mn}_2 \mathrm{O}_7$ is an oil at room temperature

$B$. $\mathrm{V}_2 \mathrm{O}_4$ reacts with acid to give $\mathrm{VO}_2^{2+}$

$C$. $\mathrm{CrO}$ is a basic oxide

$D$. $\mathrm{V}_2 \mathrm{O}_5$ does not react with acid

Choose the correct answer from the options given below :

$(I)\,K_3 [Fe(CN_6)]$   $(II)\, [Ni(CO)_4]^0$  $(III)\, [Cr(NH_3)_6]^{3+}$  $(IV)\, [Mn(CN)_6]^{4-}$ 

Choose the correct code

$2NO(g) + Cl_2(g) \longrightarrow 2NOCl(g)$

occurs in a single elementary step, we can say that
