1
Q
Suggest why it is not possible to measure enthalpy change of a combustion reaction
A
CO2 maybe be produced by complete combustion
2
Q
State Jesse’s law
A
The enthalpy change of a reaction @ constant pressure, independent of route taken
3
Q
Standard enthalpy of combustion
A
- The enthalpy change
- At constant pressure
- When one mole of a substance
- Completely burnt in oxygen
- @ standard conditions
- With reactants and products at standard state.
4
Q
State why the value for the standard enthalpy or formation of co2 is the same as combustion of carbon
A
They have the same reactants and products
5

A
Sulfur dioxide
6
Q
What can iodine reduce sulfuric acid to
A
