I need to figure out Delta H, Delta S, and Delta G for the following problem.
H2+F2 Yeilds 2HF the temperature is at 298K
You find delta Hf in a table in the back of your text.
delta Hrxn = (n*DHproducts)-(n*DHreactants)
Delta S is done the same way.
Delta Go usually is available in the same table. Or
DG = DH-TDS.
To calculate Delta H, Delta S, and Delta G for a reaction, you need to use the standard enthalpy change (Delta H°) and the standard entropy change (Delta S°) for the reaction. These values are typically provided in a table of standard thermodynamic data.
For the reaction H2 + F2 → 2HF, you can look up the standard enthalpy change (Delta H°) and the standard entropy change (Delta S°) for the formation of HF in the table. Alternatively, you can also calculate these values using bond enthalpies and standard entropy values of the atoms and molecules involved.
Once you have obtained the values for Delta H° and Delta S°, you can use the equation:
Delta G° = Delta H° - T*Delta S°
where Delta G° is the standard Gibbs free energy change, Delta H° is the standard enthalpy change, T is the temperature in Kelvin, and Delta S° is the standard entropy change.
In your case, since the temperature is given as 298K, you can plug in the values and calculate Delta G:
Delta G = Delta H - T*Delta S
Delta G = Delta H° - T*Delta S°
Make sure to convert the units of Delta H° and Delta S° to be consistent with the units of temperature (Kelvin).
If you provide the values of Delta H° and Delta S°, I can help you calculate Delta G for the reaction.
