Help for chemistry A2 core
Reechna:
Can some1 plz help??? How do you predict the order for a slow step mechanism in reaction kinetics? lik in nov08 p4 qus 2?? :-[
Lana Wolf:
theres no quest like tht...cie or edexel????

go through this: http://www.knockhardy.org.uk/assets/08KIN.PDF
it helped me....thought not to sure with the ques.
Questions like that do come....this is CIE!
Lets do some predictions : wat mite come in Paper 42 this time!! which paper 4 u guys doin?? (all this is about CIE only)
I think Chem energetics; lattice enthalpy will def. come, could b in paper 41 /42 or both!!
Somethings quantitative in electrochem..(E values, faraday) / rate of reactions(orders) mite come... =|
Mayb less calculations with pH, Ka, etc...in acid-base equilibria
just guesses from other papers....any1 know for organic A2 sections??
Reechna:
Thanks... i finally figured it out. it was cie.
i believ there will be ionic equilibria, reaction kinetics, inorganic n tough questions of organics. the rest i do not know. i hope the application questions r not difficult. i really need to work well. i didn't do my best for p2 and p5 :'(

yeah same! My chem p5 went a lil bad :( But thats just 12% weightage....hopefully p33 practical chem(12% aswel) will balance it out; p2 went good...but not best
what do u think mite come in application ques.??
