Will you check my chem answer please?

Hi, I was wondering if someone would check my homework answer before I turn it in. This is the only question I'm not completely sure about.

The Arrhenius equation is k=Ae^(-Ea/RT)

the slope of a plot of ln k vs 1/T is equal to?

My choices wer -k, k, Ea, -Ea/R, and A. I said it was -Ea/R... Is that correct?

Thanks for your help!

Update:

Thank you! I thought it was right.

    If that is grams, your answer is severe. One mole of ethane hundreds 30 grams and includes 6.02x10²³ molecules. You burned slightly over 10 moles. Watch your instruments once you do conversions.

    Yes, it is:

    Define y=1/T, then

    ln k = ln A -Eay/R

    so

    (d/dy)ln k=-Ea/R
