rates equations Flashcards
what is zero order
changing concentration has no affect on the rate of reaction it is said to be zero order with respect to the rate reaction
what is 1st order
concentrations of reactants is directly proportional to rate
what is 2nd order
reactants ^2 proptional to the rate
what is the factor that effects k
the temperature
what two methods can be used to determine the order
continuous monitoring method
initial rates method
continuous monitoring method
what are the 2 ways to measure progress of a reaction
taking samples at regular intervals
using a visble indicator
how to stop reaction when using continuous monitoring
add a large volume of cold distilled water this will cool and dilute the reaction decreasing the rate
what graph can you plot after a continuous monitoring experiment
concentration time tangent graph
what is changed in an intial rates experiment
concentration
what is gradient equal to in the arrhenius equation
-Ea/R
what is the y intercept equal to in the arrhenius equation
LnA
what is the rate determine step
the step where the species matches the species in the rate equation
