Consider the intermediate equations:
What must be done to calculate the enthalpy of
reaction? Check all that apply.
The first equation must be halved.
C(s) + O2(g) → C02(9) ΔΗ, = -393.5 kJ
200(g)+O2(g) → 2002(9) AH2 =-566.0 kJ
2H20(g) → 2H2(g) + O2(g) AH, = 483.6 kJ
With the overall reaction:
The first equation must be reversed.
The second equation must be halved.
The second equation must be reversed.
The third equation must be halved.
The third equation must be reversed.
C(s) + H20(g) → CO(g)+H2(g)
AHxn = ?
What is the overall enthalpy of reaction?
