Did you do it like this?

2HI--> H2 +I2 I 1.6m 0 0 C -x X X E 1.6x X X k=x^2/ (1.6-x)^2 k=1.42m

Make snese

No, I get the equilibrium expression for HI to be 1.6-2x
JoannaBlackwelder
  • JoannaBlackwelder
Since 2 moles of it decompose for each 1 mole of H2 and I2

  • anonymous
Remember 2 moles HI so ()^2

Look at my work

2HI intial, when you have any number of moles you take it to the the power, example 3HI then (HI)^3

@n648c788 what chemistry classes have you taken?
anonymous
  • anonymous
The decompsition just means you will make the HI -x, and H x, Ix
anonymous
  • anonymous
All but Organic is what I know best, but If I see examples I can solve old problems
anonymous
  • anonymous
HI would be -2x not -x
anonymous
  • anonymous
Yeah you are right little error, but it is worked the same way
