K notation

Hi all! When doing work for the test, let's say I forget to use a subscript at some point when I am calculating K, how much will that count against me? Also does anyone have any tips for remembering specific subscripts? Thx

I don’t think you’ll get marked down for not using subscripts. I could be wrong, but I think it is fine to just use K in these kinds of problems, like in the homework. I guess since we were using concentrations it would be Kc, but I wouldn’t worry about it! I bet you did well :)

it probably won't count against you as long as you keep track of which K you're working with, e.t.c; I think in terms of concentration, I think Kc you can remember as c=concentration, Kp as p=pressure (equilibirum). it shouldn't be too big of an issue!

I don't think they will deduct points unless you're using both types of K in the problem.Then they will get confused. A way that I remember is "Kc- c is for concentration" and "Kp p is for partial pressures". Same with deltGr- r is for reaction.

Thanks for the feedback! I'll try to just stick to K
