Definition of zero order reactants
Check what you remember
Read the wording for your board, then hide it and explain zero order reactants in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Changing the concentration of such a species leaves the rate unchanged, so its concentration has no effect on the rate.
