What will be the enthalpy of combustion of carbon to produce carbon monoxide on the basis of data given below: C(s)+O2(g) → CO2(g) - 393.4 kJ CO(g)+(1/2)O2(g) - 283.0 kJ

Question

What will be the enthalpy of combustion of carbon to produce carbon monoxide on the basis of data given below: C(s)+O2(g) → CO2(g) - 393.4 kJ CO(g)+(1/2)O2(g) - 283.0 kJ (A) + 676.4 kj (B) - 676.4 kj (C) -110.4 kj (D) + 110.4 kj

C+(1/2)O2 → CO is obtained by (i) - (ii). -393.4-(-283.0) =-110.4 kj

Q. What will be the enthalpy of combustion of carbon to produce carbon monoxide on the basis of data given below :
$C_{(s)} + O_{2 (g)} \to C O_{2 (g)} - 393.4 k J$
$C O_{(g)} + \frac{1}{2} O_{2 (g)} - 283.0 k J$

$+ 676.4 kj$

$- 676.4 kj$

$- 110.4 kj$

$+ 110.4 kj$

$C + \frac{1}{2} O_{2} \to CO$ is obtained by $(i) - (ii)$ .
$- 393.4 - (- 283.0) = - 110.4 kj$
