substance which increases the rate of a chemical reaction but does not get used up
activation energy
minimum amount of energy required for a reaction to occur
order of a reaction with respect to a reactant
thepower to which a concentration of a reactant is raised in the rateequation
order of reaction overall
the sum of the powers to which the concentration terms are raised in the rate equation
rate constant
the proportionality constant which links the rate of reaction to the concentrations in the rate equation
rate determining step
the slowest step in the mechanism of a reaction
average ratemoldm-3 s-1/min-1
concentration/time
collision theory for reaction to occur
the more successful collisions that take place in a given amount of time, faster rate of reaction
particles must collide
must collide with enough energy to reach activation energy to be successful
must collide with the correct orientation for reaction
temperature affecting rate
increased, increased particle energy, increased number of successful collisions in a given period of time, more particles will have energy required to reach activation energy barrier
