Well, if you notice, you are at two different temperatures. You are given

Since

Therefore, you assume that **all three thermodynamic functions do not vary significantly going from** **to**

As a head start, at equilibrium we have that

#DeltaG = DeltaG^@ + RTlnQ# ,

we have that

#color(blue)(DeltaG_"rxn"^@ = -RTlnK_(eq))#

After you determine
