Question

Calculate the `\DeltaG°_(rxn)` using the following information?

(left blank because I had to leave for class)

Answer 1

`734.4K`

Explanation:

The equation to find the change of free energy of any reaction is `DeltaG=DeltaH-T(DeltaS)`. In order to find the equilibrium, all you have to do is set this equation equal to 0.

The first step is to make sure all of your units match by converting your `DeltaS` to kJ/K. When you convert that you get that `DeltaS =-0.4142 (kJ)/K`. Now we can plug these values into the equation to get `0=-304.2 kJ-T(-0.4142 (kJ)/K)`, and solve using algebra.

`304.2 kJ=-T(-0.4142(kJ)/K)`.

`-304.2/0.4142 *K= -T`

`304.2/0.4142 *K= T`

`734.4K=T`
