Calculating Equilibrium values

Postby Noh_Jasmine_1J » Tue Jan 15, 2019 11:11 am

Do you have to figure out which direction the reaction goes before doing ICE table?

If there are concentrations of both products and reactants, try to figure out Q and determine if the reaction needs to go to the left or the right. This is so you know whether or not to subtract x or add x to both sides. If only given one initial concentration on one side, assume x is subtracted from said side.

To add on, if only moles or concentrations are given for one side, it is generally safe to assume that these will be the only initial values given and that your x value will be taken away from these given values. This is because in your resulting equation, the x needs to have a reference point to another given value that must be either given or calculated using stoichiometry.
