20. Using the data provided, solve for the enthalpy change value of the target equation. Note: Include all
rough notes, show all calculations, follow the rules of significant figures, and box your final answer.
AH° = -4016 kJ
20,H,OH(1) + 90,(g) –
C(s) + O,(g) → CO,(g)
2H,(g) + O,(g)
(1)
→ 6CO, + 8H,0(1)
(2)
AH° = -394 kJ
(3)
→ 2H,0(1)
AH° = -572 kJ
(Target) 6C(s) + 8H,(g) + O,(g) → 2C,H,OH(1)

Expert Solution
Step 1

According to Hess's law , enthalpy change for a reaction is independent of pathway between initial and final states of reaction.

For a multiatep reaction , enthalpy change of reaction is equal to sum of enthalpy change of each step.
