QUESTION 8
Determine ΔH for the third reaction from the information given.
2 CO2(g)
↔ 2 CO(g) + O2(g)
ΔH = 566.0 kJ
3 CO(g) + O3(g)
↔ 3 CO2
ΔH = -992.0 kJ
3/2 O2(g)
↔ O3(g)
ΔH = ?
Key Concept: Hess's law. The enthalpy change of an overall reaction is simply the sum of the enthalpy changes for individual steps that give the overall reaction.
Write the BALANCED chemical reaction for the combustion of ethanol. Show your work!
Step 2: Use the Bond Energy method to calculate the heat of reaction.
Step 3. Your answer for Step 2 is in units of kJ/mol. You need to convert this to kJ/gram by first finding the molar mass of ethanol, and then use dimensional analysis to convert from kJ/mol to kJ/g. Show ALL your work!
