Question

For the dissociation of limestone in the slag zone of the blast furnace, the reaction is (A) exothermic accompanied by increase in entropy (B) endothermic accompanied by decrease flux used is in entropy (C) endothermic accompanied by increase in entropy. (D) exothermic with no change in entropy

Tardigrade Admin · Accepted Answer

Dissociation of limestone in the slag zone of the blast furnace is represented as

C a C O_{3 (s)} Δ C a O_{(s)} + C O_{2 (g)}

The reaction proceeds with absorption of heat and leads to increase in entropy due to formation of

C O_{2}

gas.

Q. For the dissociation of limestone in the slag zone of the blast furnace, the reaction is

exothermic accompanied by increase in entropy

endothermic accompanied by decrease flux used is in entropy

endothermic accompanied by increase in entropy.

exothermic with no change in entropy

Dissociation of limestone in the slag zone of the blast furnace is represented as CaCO3(s)​Δ​CaO(s)​+CO2(g)​ The reaction proceeds with absorption of heat and leads to increase in entropy due to formation of CO2​ gas.

Dissociation of limestone in the slag zone of the blast furnace is represented as
$C a C O_{3 (s)} Δ C a O_{(s)} + C O_{2 (g)}$
The reaction proceeds with absorption of heat and leads to increase in entropy due to formation of $C O_{2}$ gas.
