Confusion on enthalpy changesWatch
C6H12O6 + 6O2 gives 6CO2+6H20
But I’m confused I thought to work out the enthalpy change using enthalpy change of combustion u use combustion data
And not formation data
How would I go about drawing a Hess’ cycle for this
And would I put CO2 and H20 in the element box to show that they combust or just the elements Carbon hydrogen and oxygen?
I thought with enthalpy change of combustion
CO2 and h20 go at the bottom
I can’t seem to find an explanation of it online
It gave me formation data but wanted me to calculate the enthalpy of combustion
So I just use Hess’ law in the way of calculating enthalpy change using enthalpy change of formation
And calculated it using products-reactants ?
And I got -2830 kJ mol -1
