Chemistry- Rate Of Reaction Revision
- rate of reaction
- factors
- frequency of collisions
- higher temperature
- more energy will move faster
- increased surface area
- increases frequency of collisions
- more of an exposed area
- higher pressure
- same amount of particles in a smaller area
- Tangent
- y/x
- higher concentration
- increase rate of reaction
- more particles able to collide with others meaning a higher frequency of collision
- activation energy
- energy needed to get a reaction started
- high temperature?
- provides reactants with activation energy
- catalyst
- increases the reaction rate by lowering the activation energy for a reaction.
- hydro-carbons
- why?
- only made from carbon and hydrogen
- crude oil heated before?
- why?
- so it can evaporate to become a gas.
- vapours?
- cool down through condensing as it has different boiling points.
- distillation
- evaporation
- condensation
- longer chains- smaller chains
- why?
- higher demand for short chain
- more useful
