Thank you We sneak and here's your shmoop du jour
- 00:05
brought to you by the rate law rule that says
- 00:08
you can't give a movie more than five stars or
- 00:11
more than two comes up all right Suppose that the
- 00:14
reaction between species a and b has the rate law
Full Transcript
- 00:17
rate k a b squared what's the overall order of
- 00:20
the reaction and potential inches high own two three We
- 00:25
need to use the rate law to determine the reaction
- 00:27
border So let's look at this thing a little more
- 00:29
closely Rate law tells us how fast the chemical reaction
- 00:33
occurs K's the rate constant and beer the concentrations of
- 00:37
the reactant When it's like a kind of that memory
- 00:40
game right The blood more fun reaction order refers to
- 00:44
the exponents on the concentrations of the species In the
- 00:47
reaction we can look at the rate law to find
- 00:49
the reaction order with respect to each individual reactant as
- 00:52
well as for the overall reaction we'll hear The construction
- 00:56
of bee is raised in second tower and that means
- 00:58
the reaction is second order With respect to species be
- 01:02
we raise our own concentration We should be able to
- 01:04
See that there's no exponents written for species a which
- 01:08
means it's raised to the first power and the reaction
- 01:10
is first order With respect to species they will find
- 01:13
the overall reaction order We just add up the reaction
- 01:16
orders with respect to species a and b Last time
- 01:18
we checked one and two is three so the correct
- 01:21
answer is d i hope you'll give this video Six
- 01:24
stars Just keep it on the d l
