Question

Which of the following reactions can take place in the reverberatory furnace?

• A. ZnO + C $\to$ Zn + CO
• B. 2Cu${}_2$S + 3O${}_2$ $\to$ 2Cu${}_2$ O + 2SO${}_2$
• C. HgS + O${}_2$ $\to$ Hg + SO${}_2$
• D. PbCO${}_3$ $\to$ PbO +CO${}_2$

Answer 1

The correct option is B 2Cu${}_2$S + 3O${}_2$ $\to$ 2Cu${}_2$ O + 2SO${}_2$

Reverberatory furnace is used in copper tin, and nickel production

$2C{u}_{2}S+3O_2⟶2C{u}_{2}O+2S{O}_2$

Oxygen is passed through curpose sulphide to give curpose oxide.
