Question
WRITE THE COMPLETE VALUE AND DO NOT ROUND OFF THE FINAL ANSWER. INCLUDE THE SIGN (+ OR -) BUT DO NOT INCLUDE THE UNIT. 3H2 (g) + CO (g) → CH4 (g) + H2O (g) Use Hess's Law to determine the enthalpy change for this methanation reaction using the following chemical equations and the value for their enthalpy changes. 2H2(g) + O2(g) → 2H20(g) 2C(s) + O2(9) CH4(g) + 202(g) CO2(g) + 2H2O(g) AH = -802.7 kJ C(s) + O2(g) → CO2(g) AH = -483.6 kJ → 2C0(g) AH = -221.0 kJ AH = -393.5 kJ
