mine came positive 129 this was the only part in whole paper i got wrong :\ will ecf be given in the next part ?Yes -129

Justify how can the temperature and pressure one be wrong?Catalyst one will be right the other temp and pressure one will be wrong
Justify how can the temperature and pressure one be wrong?
The rate of formation of methanol would increase in each of the three caseswhat is ur answer ?????????????
going to cry
What did u write for it if u used the kinetic theory then it's right else it's wrong coz it's not an equilibrium condition as no reversible reaction was occuringJustify how can the temperature and pressure one be wrong?
I actually liked the organic questions over the inorganic ones... wasn't sure about any of the chloride shizzPaper 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)
Equilibrium had absolutely no relation with the question,it was simple O level concepts.In each of the three cases the rate of formation of methanol would oncrase because at higher temperatures rate of reaction increases,at higher pressure molecules collide more oftenly so rate of reaction increases and similarly for catalyst...What did u write for it if u used the kinetic theory then it's right else it's wrong coz it's not an equilibrium condition as no reversible reaction was occuring
spot onEffect of high pressure: The spacing of the molecules decreases. Therefore, frequency of collisions increases which leads to an increase in the rate of formation of methanol.
Effect of high temperature: This is increases the average kinetic energy of the molecules. So, proportion of molecules exceeding activation energy increases. This leads to an increase in the rate of formation of methanol.
Effect of a catalyst: This reduces the activation energy of the reaction. So, frequency of effective collisions increases leading to an increase in the rate of formation of methanol. That's about it guys. Hope it matched with you.
its mixed up 22 variant had 4 questions and apparently 21 had 5THis is Chemistry VARIANT 2 Discussion RIGHT? :O
Dude the rate of formation of methanol wouldnt increase coz the reaction was methanol combusting to give CO2 and H2O and energy.....So the rate of combustion of methanol would increase.......Equilibrium had absolutely no relation with the question,it was simple O level concepts.In each of the three cases the rate of formation of methanol would oncrase because at higher temperatures rate of reaction increases,at higher pressure molecules collide more oftenly so rate of reaction increases and similarly for catalyst...

you are confusing part a with this part the equation was CO and 2 H2 give methanolDude the rate of formation of methanol wouldnt increase coz the reaction was methanol combusting to give CO2 and H2O and energy.....So the rate of combustion of methanol would increase.......
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
