Title: Reaction Arrows
Post by: pHysiX on January 12, 2009, 05:55:16 pm

Hey. I'm totally lost with equilibrium and all. I didn't do chem year 11 =p and my teacher let me do chem year 12 =]

Anyway, my question is how do I know which arrow to use? When do I use ---->, <---->, and the one that is equilibrium?

Thanks a heap in advance. Lol chem really drives me nuts

You are in unit 3, so just use single arrows. You won't be expected to know double arrows until unit 4. This stuff was not covered in units 1/2.

to be quite frank I don't know how I did it. I guess the important thing is consistent practice papers throughout the whole year to keep the course fresh in mind.

Oh, and have friends who would bounce stuff off you.
