Question

formation of carbon dioxide hinders in calculating the heat of formation of​

Answer 1

Answer:

Correct option is

C

−283

For CO,

C+

2

1

O

2

⟶CO ΔH

CO

=−110

For CO

2

,

C+O

2

⟶CO

2

ΔH

CO

2

=−393

For the reaction

CO+

2

1

O

2

⟶CO

2

We will substract equation 1 from equation 2, we get

CO+

2

1

O

2

⟶CO

2

ΔH

CO

2

−ΔH

CO

=−393−(−110)=−283KJmol
