What constant concentrations means in Chemistry A-Level, as defined for AQA, OCR.
Definitions of constant concentrations
Exam boards and our study guides word this term in slightly different ways. Learn the version your board uses.
Check what you remember
Read the wording for your board, then hide it and explain constant concentrations in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The concentrations of reactants and products do not change, even though particles are still reacting in both directions.
The concentrations of reactants and products remain constant, and constant does not mean equal.
