how do you work out the rate of a reaction?
change in conc / time
1 of 8
what is the order of a reaction?
shows how the rate of the reaction depends on the concentration of certain substances present. The higher the power, the more influential it is.
2 of 8
rate expression for a 0 order reaction:
rate = k
3 of 8
rate expression for a first order reaction:
rate = k[A]
4 of 8
rate expression for a second order reaction:
rate = k[A][B]
5 of 8
rate expression for a third order reaction:
rate = k[A][B]^2
6 of 8
what is the effect on the increase in temperature?
and increase in K
7 of 8
what is the definition of the rate determining step?
in a multistep reaction, the slowest step will decide the rate for the whole process. This is the slowest and the rate-determining step.
