Rate determining step

Rate determining step can seem difficult to work out. But with this simple explanation you should have no more problems with this exam favourite. Come complete with a cake method too. Take a look to see what I mean!

Great analogy, it really helps understand the concept in laymen's terms

[@AlleryChemistry]

Glad you think so!

[@amya8045]

Thank you so much for making this video, it was really helpful and well explained plus after doing some chemistry I'm going to be watching the great british bake off! The analogy was pretty good actually

[@MidnightStorm4990]

Watching this playlist at 1.5 speed to refresh my knowledge on this topic the day before the exam lol

[@ramens]

deadass me rn

[@fisademha1]

Your explanation may confuse students however as you have said the slow step is the 'bake and cook' If this is so, it is step 3 of your stages and so you cannot do this slow step until you have done the first 2 steps, therefore step 1 and 2 would affect rate and be in the rate equation

[@robertpardington9591]

I thought that the rate equation was all reactants up to and including the slowest step of the reaction, am I wrong?
Great video though thanks

[@revisionpanda6826]

guys:
look at the rate equatin - rate=k[A][B]^2 or whatever
this means both A and B must be in the RDS
RDS should be something like A + 2B --> _________ (products of the steps don't matter)

[@shagufthahaider4911]

I understand the 1:1 ratio, but since RDS is the SLOWEST step, doesn't that mean step 2 needs to be the RDS?

[@MAHA-vz1kc]

only video on the topic that i understood.THANKS

[@AlleryChemistry]

You are welcome

[@kellylee5813]

Thanks. You are the man. It helped me explain my background and theory for my chem lab. Wohooo chem AP T^T

[@AlleryChemistry]

Thanks very much! Pleased they are helping. Please share, the more people they help the better!

[@israzafar4824]

Like u have made OCR year revision video. Can u make for year 2 as well please. Your year 1 slides were really helpful

[@maishaa551]

Okay without a doubt your video content/explaining is one of the strongest in all of RUclips chemistry. Only thing I would suggest would be camera angles and focus. (I find myself squinting more often than not) Also maybe wear a microphone as the audio can be scratchy sometimes. Nevertheless amazing videos!

[@oohmyyy]

these videos are great! thank you :)

[@mohammedibrahim4900]

I do not understand how the last step links to the rate orders. I mean shouldn't C4H9Br be first order and OH(negative) second order or vice versa? If so, why don't we write that as well?

[@AlleryChemistry]

Mohammed Ibrahim The rate equation was found from a practical and was shown to be first order for both. Rate expressions can only be determined from experiment. You can't look at a reaction and say what the orders are. In the exam you will be given the rate expression or will be given information so you can work it out. Hope this helps.

[@mohammedibrahim4900]

A Level Chemistry Revision Videos Ohhh I thought there should always be first and second orders mentioned. That clears things up. Thanx :)

[@DogeDogeriffic]

Actual life saver

[@linar736]

is there a more difficult/exam style version of this?

[@AlleryChemistry]

I have some exam style questions that will cover other questions.

[@kajapraveen]

Thx u so much appreciated 💓
