## ΔGionization

$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

### ΔGionization

Is there a different way to calculate ΔG ionization?

I don't think so! It should be the same as the regular way of calculating standard gibbs free energy.

I believe that deltaG ionization is calculated the same as normal standard gibbs free energy.

### Re: ΔGionization

Would delta G ionization be the same for other temperatures besides 25 degrees Celsius? Let's say for example you're taking the delta G of ionization for a reaction at 30 degrees Celsius, would you use just the standard equations for delta G? I hope that question makes sense, please someone help I want to know.

I'm pretty sure all standard state quantities are dependent on time. Gibb's free energy change is a function of temperature so at different temperatures, you would have different energies.

In that case, how would you calculate Gibbs Free Energy at non-standard temperature?

I don't think there is another way, calculating for delta Gionization is the same as calculating for delta Go.

Nope! you can use any of the equations for calculating deltaG. I think it's just a way to label it relating to the reaction.

Thank you! I understand now:)

I don't believe there is another method, and there shouldn't have to if you are given all the right information on the midterm/homeworks!

As said by others, I don't believe so :(
