Studied by 10 people0 order: differential rate law
rate = k
0 order: integrated rate law
[A] = -kt + [A]0
0 order: half-life
t1/2 = [A]0/2k
When ____ is linear, it’s 0 order. What is the slope?
the plot of [A]
slope = -k
units for 0 order
M/sec
1st order: differential rate law
-∆[A]/∆t
rate = k[A]
1st order: integrated rate law
ln([A]0/[A]) = kt
ln [A] = -kt + = ln [A]0
[A] = [A]0e-kt
1st order: half life
0.693/k
units for 1st order
1/sec
When ____ is linear, it’s 1st order. What is the slope?
ln [A] is linear
slope = -k
2nd order: differential rate law
rate = k[A]2
2nd order: integrated rate law
1/[A] = kt + 1/[A]0
on formula sheet
2nd order: half life
1/k[A]0
use final concentration of previous half life
units for 2nd order
1/M × sec
When ____ is linear, it’s 2nd order. What is the slope?
plot of 1/[A] is linear
slope = k
