Calculating Equilibrium Composition

Postby Jacqueline Duong 1H » Thu Mar 14, 2019 4:36 am

When using the quadratic equation to calculate the equilibrium composition, how do we know which of the two values is the right one for x?

Whichever value that leads to no negative concentrations when plugging back in to the ICE table.

After you find the x values, you plug it into the ice table. Only one of the values will give an answer that makes sense because the other x value will give a negative equilibrium concentration, which is not possible.
