- Homework Statement
- given:
C + 2H2 -> CH4 What is the heat of reaction
- Relevant Equations
- C + O2 -> CO2 delta H = -393.5 kJ/mole
H2 + 1/2 O2 -> H2O delta H = -285.8 kJ/mole
CH4 + 2Os -> CO2 + 2H2O delta H = ?????
the book says delta H = -890.8 kL/mole
Since the heat of formtion of H2O is -285.8 and the heat of formation of CO2 is -393.5 I thought that the heat of reaction CH4 + 2O2
should be -393.5 + 2(-285.80 = -965.1
Where am I wrong?
should be -393.5 + 2(-285.80 = -965.1
Where am I wrong?
