Answer 1

Step-by-step explanation:

Given :

(I) Fe

2

O

3(s)

+ 3CO

(g)

→ 2Fe(s) + 3CO

2(g)

; Δ H=−26.8kJ

(II) FeO

(s)

+ CO

(g)

→ Fe

(s)

+ CO

2(g)

; Δ =−16.5kJ

On multiplying equation (II) with 2, we get

(III) 2FeO

(s)

+ 2CO

(g)

→ 2Fe

(s)

+ 2CO

2(g)

; ΔH=−33kJ

On substracting equation (IIII) from, I we get

(IV) Fe

2

O

3(s)

+ CO

(g)

→ 2FeO

(s)

+ CO

2(g)

; Δ H=−26.8−(−33)kJ=+6.2kJ

The value of ΔH for the reaction (IV) is + 6.2kJ.
