Rate of reaction
Cards in this deck (3)
- 1Increasing temperatureIncreasing the temperature increases the rate of the reaction in both directions because at higher temperatures particles have more energy and move faster
Particles have more frequent collisions
More collisions have total energy of at least the activation energy so they are successful - 2Increasing pressureIncreasing the pressure increases the rate of reaction in both directions
because there is an increased number of particles per unit of volume
so increased collisions per unit of time - 3Adding catalystA catalyst provides an alternative route with a lower activation enthalpy
This means the rate of reaction is increased (an equal amount in both directions)
