Ice table coefficients

Postby Tinisha 1G » Wed Jan 16, 2019 5:36 pm

Is the coefficient of the change row in the ICE table always match the stoichiometric coefficients of the reaction?
Thanks!

Yes.

I'm not sure if I'm correct but to get the change row in the ICE table, isn't it always going to be either -x or +x? I haven't encountered a problem where there are coefficients in front of it. But I am also confused on this topic.

If you look on the example 5I.3 7th ed on p.419-420 you see in the change portion of the ICE that there can be a +2x or -2x. These come from the stoichiometric coefficients of the chemical equations

Are there any differences in solving ICE tables for acid-base reactions and gases? Other than keeping in mind partial pressures

For all coefficients in the ICE table, you would follow the stoichiometric coefficients. I think Dr. Lavelle also explained an example in class which used +2x or -2x also.

you have to balance the equation and look at the stoichiometric coefficients to determine that value
