ICE chart

[inlovewithchemistry]

Can both molar values and concentrations go into the ice chart? I have seen it used both ways in the homework and it was confusing me.

Yes, molar values and/or concentrations can go in the chart. However, whatever you decide to use, you should keep it consistent throughout the ICE chart. In addition, if using molar values it is common to convert the molar values into concentrations at the end to solve for the equilibrium constant.

Concentration is preferable but you do molar values only if all of the numbers are consistent. You can do both ways as long as you keep them consistent throughout the problem.

Either can be used, however, it should be consistent throughout the entire problem.
