Rate of reaction

external pratice

catalyst definition

provides an alternative lower activation energy pathway for the reaction to occur without being consumed in the process.

catalyst expl

more collisions occur with greater than the Ea - so a greater proportion of successful collisions/s

Catalyst diagram

Concentration

more particles/mL

more collisions/s

Surface Area

more particles exposed

more collisions/sand increased reaction rates.

ROR - Rate of reaction comparison statement

there was the same AMOUNT of reactants in both reactions therefore the same AMOUNT of products are formed.

Temp

Faster —> more collisions/s

more kinetic energy

more collisions occur with greater than Ea

more successful collisions/s
