I'm sitting my English A Paper 1 and Paper 2 this week.... I've been self studying at home as a mature student, mainly due to time and cost implications.... am now really panicking and wonder if anyone can tell me whether there has been a main Anthology focus if you are doing yours in lessons? I'm guessing that those in the past 3 papers I've seen are unlikely to come up but cannot find out what was in Jan 2013 paper.
If anyone can shed some light to help me find a quick area of focus for Thursday's paper 2 I would really appreciate it. Equally appreciate if anyone could put my mind at ease, I do write presentations, business papers, HR policies, marketing items and have worked in various sectors with exposure to a lot of poorly written English and need grammatical adjustments so am I worrying for nothing. What is worrying me the most is that I did NOT want to do anything literature based and notice that this is quite literature heavy..... GRRR might need to look at an alternative if I don't achieve a C in this!

Question about Chemistry.
How come the efficiency of the Haber process in reality is 15%, instead of the theoretical 30%?
So, in other words, only 15% of Ammonia is produced, instead of the theoretical 30%.
Are there like factors affecting it or something? ??? ??? ??? :o :o :'(
NotAbod:
There are reasons for that. Unfortunately, I don't remember any of them right now.
But let me try.
Experimental error? Theoretical calculations assume you do no experimental errors in masses or volumes of reactants for example. So 30% yield is when your experiment is completely perfect, which is impossible.
Check your textbook, there must be something about that.

I thought Chemistry IGCSE today was incredibly easy. Easier than most past papers..

same- although I know I made one or two silly errors
