Resumo de Recurso
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
