ICE table question

Postby Alexia_Vanegas_1G » Sat Nov 19, 2016 5:19 pm

When completing the ice table, if the initial concentration of a molecule is given and it has more than one mole, do you multiply its initial concentration by the number of moles the molecule has in the balanced equation before inputting it in the ice table?

For example: 2BrCl (g) ⟷ Br2 (g) + Cl2 (g) and the initial concentration is 5 M. Do you multiply it by 2 before putting it in the ice table?

I don't think you would. Multiplying by the moles applies to the change in molar concentration.

Confirming what Brandon said, you do not multiply the initial concentration by the number of moles the molecule has. The number of moles the molecule has is relevant when you're calculating the change in molarity (C part of the table) as well as in your equilibrium constant (K) calculations.
