For the general reaction: aA → Products
Zero Order
First Order
Second Order
Rate Law
Rate = k
Rate = k[A]
Rate = k[A]2
Integrated Rate
Law
[A] = -kt + [A]0
ln [A] = -kt + ln [A]0
[A]-1 = kt + [A]0
-1
Plot Needed For
Straight Line
[A] versus t
ln [A] versus t
[A]-1 versus t
Relationship of
Rate Constant to
the Slope of
Straight Line
Slope = -k
Slope = -k
Slope = k
Half-life
t1/2 = [A]0/2k
t1/2 = 0.693/k
t1/2 = 1/(k[A]0)
