final states of the reactants and products
- rules for creating a CYCLE.
- 1. if its not given in the
question you MUST right
and equation for the
unnown reaction/
enthalpy.
- 2. you MUST write
equations for any
given data
- 3. write the unknown
(equation) across the top
- 4. match up equation to unknowns and
check arrows pointing in the right direction
- 5. CLOCKWISE=
ANTICLOCKWISE.
