Definition of Unchanged energy distribution
Check what you remember
Read the wording for your board, then hide it and explain Unchanged energy distribution in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The proportion of collisions with energy greater than or equal to the activation energy is fixed by temperature, so the energy distribution remains untouched and the Maxwell–Boltzmann curve is unchanged.
