2.3 Kinetics Flashcards
1
Q
what does the rate of a chemical reaction depend on?
A
the concentrations of the reactants
2
Q
how do you determine the overall order of a reaction?
A
only from experimental data
add together the orders
3
Q
what are the effects of catalysts, temp or conc on k?
A
k is constant for changing concentration
k changes if temperature or catalyst are changed
4
Q
how do reactions usually occur?
A
by steps called a reaction mechanism
5
Q
how is the rate of reaction determined from a reaction mechanism?
A
it is dependent on the slowest step
6
Q
what is the slowest step in a reaction mechanism called?
A
the rate determining step
