Half Term 2 Flashcards
How to calculate Concentration
Mass divided by volumme
Catalyst
Lowers the activation energy
Enzymes
Proteins that act as biological catalysts
Why are catalysts useful
They speed up a reaction without being changed or used up
Dependent variable
The one thing that happens because of the independent variable
Controlled variable
Everything that stays the same
Independent varianle
The one thing you change
What increases the rates the rate of a reaction
Catalyst, surface area, temperature, concentration, pressure
What is a catalyst
A substance that speeds up the rate of a reaction
How does a catalysts work
Provides an alternative reaction pathway with a lower activation energy
Collision theory
When particles collide with enough energy to break bonds and make new ones or new products
Oxidation
The gain of oxygen
Reduction
Loss of oxygen
How do a catalyst work
They Provide an alternative pathway with a lower activation energy
