Rate of reaction Flashcards
what is active energy
the minimum energy required for a collision
what is enthalpy
chemical energy
how does concentration affect rate of reaction
-particles are closer to each other -increases the frequency of successful collision
-rate of reaction increases
how does catalyst affect rate of reaction
-provides an alternative route for the reaction which involves a lower activation energy
-lowering the activation energy which greater proportion of the particle exceeds activation energy
how does temperature affect rate of reaction
-particles have more kinetic energy
-more successful collision
-ROR increases
mean ROR = ______/time
amount of reactant used
how does SA affect ROR
-more particles are exposed to the other reactant
-there is a greater chance of particles colliding
