Year 12s: what will be the first way you research your future options? >>

EDEXCEL Chemistry Topic 4b: tests for halogens

Hi everyone!
I understand that Year 13s have mocks but if someone could please help me out wth this I will be eternally grateful!
So Topic 4 has all the tests and stuff, and I'm currently stuck on this specification point,
"13. understand the following reactions:
i solid Group 1 halides with concentrated sulfuric acid, to illustrate the trend in
reducing ability of the hydrogen halides"
What I want to know is do I have to know all the reaction (acid-base and redox and half equations) for this test, because I'm stressing because I know I'll muck u remembering it! Iodine literally has 4 equations and 4 half equations!
I'm praying that i don't need to memorise these (but if I do then I need to get a move on, and if you could give me some advice on that it'd be appreciated)
Thanks! xxx

You either need to memorise them, or better yet work them out (as all you need to know to do this option is recall what oxidation states the halogen can go to).
