Which of the following reaction is Not nentropy driven with reference to extractive metallurgy? (unbalanced reactions)

A

$CaC{O_{3.}}MgC{O_3}\left( s \right) \to $

B

$C\left( s \right) + C{O_2}\left( g \right) \to $

C

$C{u_2}S + {O_2}\left( g \right)\xrightarrow{\Delta }$

D

$Ni{(CO)_4}\left( g \right)\xrightarrow{\Delta }$

Solution

$\mathrm{CaCO}_{3} \cdot \mathrm{MgCO}_{3} \rightarrow \mathrm{CaO}(\mathrm{s})+\mathrm{MgO}(\mathrm{s})+$ $2 \mathrm{CO}_{2}(\mathrm{g})$

$\mathrm{C}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{CO}(\mathrm{g})$

$2 \mathrm{Cu}_{2} \mathrm{S}+3 \mathrm{O}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{Cu}_{2} \mathrm{O}+2 \mathrm{SO}_{2}(\mathrm{g})$

$\mathrm{Ni}(\mathrm{CO})_{4} \stackrel{\Delta}{\longrightarrow} \mathrm{Ni}(\mathrm{S})+4 \mathrm{CO}(\mathrm{g})$
