Pseudo First Order Reactions - Kinetics

[@YounseoChoi-pe7bd]

I normally don't write any comments for educational videos or chem videos but you are the only video that made me understand this concept!! My professor failed, my textbook failed, and other videos also failed to explain but you did! Thank you so much for this video!!!

[@_oneshot_00_30]

This was exactly what I was looking for! I’m so glad I found this video the day before my kinetics lab.

[@1light4love]

oh man you're doing one too??! this is crazy. I thought we wre only supposed to solve for the rate order law of the reactions!! lol wishful thinking.
Thabks CHEM guru!! I'll be back!

[@boobalarasuvelu9804]

I like the way Guru explained the concept

[@ChemistryGuru]

Thank you for the compliment! 😄

[@Dina-he1uc]

thank u so much for this i have been struggling to understand with my profs lectures but this is realy easy to understand, thank you!!!

[@Kashman_Global_TV]

Thank you very much for the wonderful explanation. However, if I am dealing with industrial wastewater treatment in batch adsorption and the concentration is constant in the wastewater, where I cannot perform 'the effect of different concentrations on water treatment, how can I get the value of qe?

Thank you, I was struggling to understand this.

[@ChemistryGuru]

Thank you Tasneem! Glad you found this video helpful! :)

Great,!!

[@pohchinghong4625]

Hi, if I was given varying concentration of A and light intensity in different sets of experiment, can I consider light intensity as constant and make the reaction a pseudo first order reaction? (Assume the reaction is 1st order wrt A)

[@ChemistryGuru]

Hi Ching Hong, if the rate of the reaction is affected by light intensity, then in principle pseudo first order reaction concept should be applicable to light intensity as well. ie as you have mentioned, if light intensity is very high, then rate of reaction becomes independent of light intensity, so will become first order wrt A.

[@abraralharbi6]

thanks

[@henrywang5075]

Hi, for this question since the concentration is unchanged, wouldn't it be easier if we took rate 2 divided by rate 1, which would cancel out the concentration of A and k, thus giving the proportion of the rates directly? Thanks for the video!

[@ChemistryGuru]

HI Henry yes we can do that also! That would give a direct link between rate and conc of B. For the video we are trying to establish a relationship between half life and conc of B, so the explanation is a bit longer :)

[@leonaasgarpour9866]

Thank you!

[@usmanghori8465]

which software do you use ?

[@ChemistryGuru]

I'm using Camtasia for video editing :)

[@jayanth938]

hi, half life refers to the half life of A right?

[@ChemistryGuru]

yes half life with respect to reactant A

So foreigners also has to study this
