opps i forgot the ln...

ok so delta S is -33.543 and delta H is 65649 J? i'm still a bit confused about this b/c in the lab, it says to plot ln ksp vs 1/T, and find these values using the equation of the line. is what you graph basically the same thing? if i were to graph ln ksp vs. 1/T, then my slope would be 775.4, and delta H would be -6446.47 which is not the same.
