Rate of Chemical Change Flashcards
What can make data more reliable
Controlling variables and repeating
What is activation energy
The minimum energy required for a reaction to happen
What effect does concentration have on rate of reaction
The greater the concentration, the greater the number of reactant particles there are. There will be more collisions thus increasing the likelihood of a successful collision
What effect does temperature have on the rate of reaction
A greater temperature means more energy is available. More kinetic energy means the particles move more. This lowers the activation energy and more successful collisions are likely
What is needed for a successful collusion
Particles colliding at the right speed, with enough power, at a certain angle
What is a catalyst
They speed up reactions without being a part of it. The catalyst is not a product or reactant
