    I came here to say thank you, I visited your channel on first year of the university for calculus and chemistry and i learned a lot of what my professors would never be able to explain. Now I graduated, almost forgot about the classes, but i will never forget you and your channel and i will keep supporting, thank you and i hope you have a great day. ❤️

    at 13:48 I appreciate you mentioning this again (that M is mol/L ie Molarity) because sometimes people forget and just get more and more lost as the lecture continues. it helps to reinforce the knowledge by repeating sometimes.

      Yeah, but there are professors with 20 years of teaching expertise, yet they never changed their ways of teaching. It's an acceptable excuse for a beginning one, but not when you're 25 years into the job and still can't notice most of your students don't understand anything.@@2jnp

    14:30, the answer supposed to be positive because [NO] is decreasing with time therefore we're supposed to multiply -8.2 x 10³ m/s with a negative sign (-), inclusion the final answer is 8.2 x 10³. Look it up in Zuhmdahl 9th Ed, page 555-556

      I came through the comment section for this but couldnt find the answer either

    • @gabrielragum
      @gabrielragum 3 ปีที่แล้ว +13

      The problem asks for the average rate of disappearance of NO in the first 20 seconds. The average rate of disappearence is defined as -Δ[R]/Δt, where Δ[R] is the change in concentration of the reactant.
      The reason you don't divide by the coefficient is because that would give you the average reaction rate (Rate = 1/2 (-Δ[NO]/Δt)), not the average rate of disappearence of NO.
      Therefore, for NO, -(0,586 - 0,750) M / 20 s is the final answer, which should be positive, not negative like in the video.
      Also I believe there is a mistake in the chemical equation (although it doesn't matter for this problem), the product of this reaction should be 2NO₂, not 2NO.
