Chemistry Paper 2

[Hifsa]

How did it go everyone?
Just wanna know whether the percentile's gonna be low or high

 

[roadtrip9o9]

was good .. threshold around 50 for sure

i guess.... its gonna fall this year...!!!

which variant are u talking about ?

Paper 22

 

[Hifsa]

was good .. threshold around 50 for sure

I don't remember the question number, I guess it was 2, the one they asked about the conditions for the formation of methanol, that was confusing, cuz I wasn't sure whether we need to apply Le Chatlier's principle or not... :/
What did you write in that?

 

[roadtrip9o9]

i drew a basic hess cycle

 

[Hifsa]

N

i drew a basic hess cycle

Nooo, the reasons for the conditions they gave us..

 

[Preetty lady]

I got it wrong! They said use boltzman! =( frust!

What did you write in that?

We were not supposed to use the Le chatlier's principle because it was irreversible reaction was not in equilibrium.
Le chatlier's principles are used for reversible reactions in equilibrium

Paper was comparatively easy from the past few years.
Organic questions were very well designed and most of the candidates including me lost marks in the organic questions.
A lot of people did very well while a lot of people messed it up too

Grade threshold
46 - 48 - A (Most probably)

Nooo, they never mentioned boltzman cuyrve maybe we're not talking about the same variant here

Ohhh... for temperature and catalyst I didn't use that, but for pressure I used it BUT I wrote 2 answers for that, so I guess they will give me marks for that,
And btw, that emperical formula that we had to finddd...... what was that? I got C10H13O11

me toooooo

 

[Hifsa]

me toooooo

what about your empirical formula?

 

[dJB]

what about your empirical formula?

C6H8O7

 

[Ahmed Tariq]

The empirical formula was something like C6H8O7. Don't remember exactly.
And in the formation of methanol question, Le Chatelier's principle definitely had to be taken into account for temperature and pressure.

 

[Hifsa]

C6H8O7

Holllyyyy motherr!!!! It was for 3 marks

it must be C6H9O7,

 

[dayeed]

nahi it was C6H8O7 for sure 100% ,,,,, woh enthalpy change kia tha?

 

[shah0007]

enthalpy change was -129 i guess.
