Quick Revision - The equilibrium constant Kp

[@jackgilbert9682]

Hi MaChemGuy. Got my first OCR Chemistry A level paper in just under 3 weeks. Just a quick question as to when you will be finished making the quick revision videos as they are really helpful! Thank you sir.

How did you do

[@RohailMemon]

@@kdg918im okay wbu

[@jaimesumner8871]

HI! Love these videos, For the Kp calculation how did you get 8.51 as I can not get that answer. I keep getting 0.0013

You’ll have to send me a photo of your working out. Message me on Instagram

So is it okay if my mole fractions do not exactly add up to give 1... if they are around 1 (i got 0.9998) then i am okay to use that?

[@MaChemGuy]

Fine

[@user-kx6sl2sr7u]

is the Kp explanation for shift in equilibrium same as the Kc explanation

Have you watched this video? kzbin.info/www/bejne/iF68hYafZplgb5o

@@MaChemGuy Yes sorry I was meant to delete this comment after I saw the other video. Very helpful 👍

[@Ok-cq7zq]

i’m confused what the units of kp are because i’ve seen in some questions they state them as atm but some kpa??

[@MaChemGuy]

Ok Can be both, depends what the pressure is given in

[@successimafidon8384]

Sir how about catalyst does it affect kp

[@MaChemGuy]

Only temperature

Are these videos good for AQA?

[@MaChemGuy]

Absolutely!
