How can I do this problem, even though I am given #DeltaH# and #DeltaS# at the wrong temperature? For a certain reaction, #DeltaH_(rxn)^@ = . . . # and #DeltaS_(rxn)^@ = . . . # at #25^@ "C"#. Calculate #DeltaG_(rxn)^@# and #K_(eq)# at #37^@ "C"#?

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
As a head start, at equilibrium we have that
#DeltaG = DeltaG^@ + RTlnQ# ,
we have that
#color(blue)(DeltaG_"rxn"^@ = -RTlnK_(eq))#
After you determine
