Question

Match the reactions taking place in blast furnace with temperature - range of operations
        Column - I                                          Column - II
(a) C + CO2  →  2CO                               (p) ≈ 1000oC
(b) FeO + CO  → Fe + CO2                    (q) ≈ 800oC
(c) CaO + SiO2  →  CaSiO3                   (r) ≈1800oC
(d) Fe3O4 + 4CO → 3Fe + 4CO2          (s) ≈ 400oC
Select the correct option from the given codes.

Options

A.(a) → p
(b) → q
(c) → r
(d) → s
B.(a) → q
(b) → p
(c) → r
(d) → s
C.(a) → s
(b) → q
(c) → r
(d) → p
D.(a) → p
(b) → q
(c) → s

Solution

(a) C + CO2 → 2CO → 1000oC
(b) FeO + CO → Fe + CO2 → 800oC
(c) CaO + SiO2 → CaSiO3 → 1800oC
(d) Fe3O4 + 4CO → 3Fe + 4CO2 → 400oC
