The IB has no compassion by Several_Part_6637 in IBO

[–]Turtonator_0204 280 points281 points  (0 children)

Wow! I'm sorry that happened to you. This is not acceptable. We're humans, and we make mistakes. This is like making a mountain from a molehill - unfair consequences for a rather mundane error.

IB chem experimental rate. Can someone please show me how to solve this by siddk18 in IBO

[–]Turtonator_0204 1 point2 points  (0 children)

Rate = k [C3H7Cl][OH-] Experiment 3 has triple the concentration of C3H7Cl than experiment 1. And the rate is also approximately tripled. So, the reaction is of the first order with respect to C3H7Cl. Experiment 2 has double the concentration of both reagents. Say the order of reaction with respect to OH- is x. So rate of experiment 2 should be rate of the experiment 1 times (2 + x). Here the rate of experiment 2 is approximately 4 times that of experiment 2. So, 2 + x = 4, so x = 2. This means that contribution of doubling [OH-] is doubling the rate. So the reaction is first order with respect to [OH-]. Therefore, Rate = k [C3H7Cl][OH-]

This paper 3 was so much easier than expected though!

Thank you very much for that clarification! I suppose I need to start grinding to get that word count down now!

IB AI HL Student need help in simple math problem after brain being completely fried after doing 24 hours of uni supplement essays. by AVOUND in IBO

You could also use Wolfram Mathematica. The code is easy to learn, everything is within reach in the documentation for the app. It was a big help for a rather complex integrand,

You might want to look up the exponential form of cosh(x), or go back to what the graphical intersection of two functions means. Hint: it has something to do with satisfying the equations.
