I had to make a graph using lnK vs 1/T and find the slope. The slope was -1.23e4 and now I have to find Ea.

Question

Do I divide the slope by R

Answer 1

slope = -Ea/R

Answer 2

I did -1.23e4 / 8.314 = -1479.43
and I tryed 1.23e4 / 8.314 = 1479.43 but my online homework keeps saying that its incorrect.

Answer 3

Nevermind I know what I did wrong. I had to divide my final answer by 1000 to get kJ.
