The reaction describing the formation of ozone from oxygen is shown below.

Question

3 O2(g) <--> 2 O3(g)

Calculate Grxn at 288 K for this reaction in a flask where
[O2] = 3.419 x 10-2 M and
[O3] = 5.783 x 10-4 M.
Assume G° = 326 kJ.

Use molarity to construct the reaction quotient, and express your answer in kJ.

Answer 1

DG = DGo + RT*lnQ
Q = (O3)^2/(O2)^3
Use 8.314 for R
