    You da real MVP. My chemistry II professor did not mention the forms of arrhenius equations, so I was tumped when I learned from a tutor that we had to use a completely different formula for the practice problem we had.

    i only need to learn 1 form but i understand the equation so much better having gone through the other forms ty friend

    why didnt you cancel the "Ea/R" from both sides for the rate constant of two different temperatures?? its at 6:17

      You won't be able to eliminate EA/R terms as they're multiplied by temp respectively however equation can be made simpler by eliminating lnA term which is independent of temp

    Why did you decide to subtract ln(k)'s? My first idea would have been to set the equations equal to each other.

    i believe you made a mistake on the Arrhenius equation form, wouldn't it be Ln(K2/K1)=-Ea/RT(1/t1 - 1/t2) if you put the k2 on top?

      +Everett Reyna the equation you are thinking of is how it is usually written, with a postive Ea/R term, the video is not wrong it is just the same equation but they left the negative in the Ea/R term

      thanks for the explanation, i was curious

    can someone tell why lne got cancelled

      its mathmatical rule to give an easy explanation.
      you cancel ln of e but leave the exponents that e had. as per video

      My dumbass thought someone called lne got cancelled. I need to get off twitter before it impacts my life even further.

    what is e?

      Ea is activation energy and e is exponential
