Question

3. A schematic representation of enthalpy changes for
the reaction, C graphite) +- O2() → CO (g) is given
below. The missing value is
Cgraphite + O2(g)
??
CO(g) + 220(9)
– 393.5 kJ
CO.(a)
/ -283.0 kJ
(1) + 10.5 kJ
(3) - 110.5 kJ
(2) – 11.05 kJ
(4) – 10.5 J​

Answer 1

Answer:

Answer is -110.5 kJ

Explanation:

Since enthalpy is a state function therefore it does not depend on the path . Thats y the enthalpy of direct method and indirect method of formation of product ( i . e here CO2 ) will be same so thats y.....

-393.5 = X + (-283 KJ)

X = -110.5 KJ

Answer 2

Answer:

-110.5KJ

Explanation:

Enthalpy is a state function it doesn't depend on path.The enthalpy of direct method and indirect method of formation of product ( i . e here CO2 ) will be same so thats y.....

-393.5 = X + (-283 KJ)

X = -110.5 KJ
