Module: Chemical Equilibrium Part 3

Postby Shannon Asay 1C » Wed Jan 08, 2020 1:53 pm

When solving an ICE table and solving for x, when do you know you can simplify a quadratic or cubed equation, and why can you do that?

You can simplify the equations when K < 10^-4. This is because a small Kc value means not much product is formed and that the "x" value is small and negligible when trying to approximate equilibrium concentrations.

Typically a good rule of thumb is to always assume "x" is negligible when you have a cubic equation so that you can just solve a quadratic equation as normal.
