Calculating Equilibrium values

[Noh_Jasmine_1J]

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

[Cole Elsner 2J]

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.

[Anna O 2C]

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.
