  • Is a reaction feasable? Gibbs free energy
    • G  =  H  -   T S
    • S = In JK  mol  so we need to devide it by 1000 when doing calculations
    • If delta G = 0 or minus the reaction is feasable
    • Units are always Kjmol
    • FACT!!!!
      • If delta G is 0 or minus, this doesn't mean a reaction is ACTUALLY going to happen as the rate may be very slow or the reaction might have a high activation energy
    • To work out temperature
      • Rearrange equation bearing in mind that delta G is always 0
