WebThe correct answers are 0; -0.16 respectively but i'm getting a different one. Calculate delta G and delta A for the freezing of 1.00 mol of H2O at 0oC and 1 atm. The heat of fusion of water at 0oC is 6002 J mol-1. The density of ice at 0oC and 1 atm is 0.917 g cm-3, and that of water at the same conditions is 1.000 g cm-3. WebDelta G= DeltaH - T (Delta S) Delta G= Delta H - T (Delta S) Things you can learn from above equation. **This equations applies to standard and non-standard conditions. -If a reaction reaches equilibrium that means Delta G=0. So iff you rearrange, you find that. Delta S= Delta H/ T @ equilibrium. -If you have water at 1atm at -50 degrees celsius.
