Question

A schematic representation of enthalpy changes for the C text(graphite) + (1/2)O2(g) → CO(g) reaction, is given below. The missing value is (A) + 10.5 kJ (B) - 11.05 kJ (C) - 110.5 kJ (D) - 10.5 J

Tardigrade Admin · Accepted Answer

Since enthalpy is state function, ΔH + (- 283.0 kJ) = - 393.5 kJ or, ΔH = - 110.5 kJ

Q. A schematic representation of enthalpy changes for the $C_{(graphite)} + \frac{1}{2} O_{2} (g) \to CO (g)$ reaction, is given below. The missing value is

+ 10.5 kJ

- 11.05 kJ

- 110.5 kJ

- 10.5 J

Since enthalpy is state function,
$Δ H + (- 283.0 k J) = - 393.5 k J$
or, $Δ H = - 110.5 k J$
