Document Summary

Chm 11600 - general chemistry - lecture 10_chemical equilibrium. Determine direction of reaction: q vs. k. Set up ice reaction table: beware of stoichiometry! Assume x is negligible for additions and subtractions. If x is not negligible, solve explicitly (usually using quadratic formula) 1 = same amount of products and reactants. If going from mostly reactants to 1, change is +x. If going from mostly products to 1, change is -x. You are most likely to start with all of the reactants and zero products (the recipe ) If the k is small, then x (change) is likely to be small and you are likely to be able to use the approximation. If k is intermediate, do the math,
