1st order diff rate law
r = k[A]
1st order k is
s-1k
1st order intigrated rate law
In[A] = -kt + In[A]o
in first order intigrated rate law how do you solve for k?
k = In[A]o-In[A]/T
1st order half-life
0.693/k
2nd order diff rate law
r = k[A]2
2nd order k is
m-1 x s-1
2nd order intigrated rate law
1/[A] = kt + 1/[A]o
2nd order half-life
1/[A]ok
0th order diff rate law is
r = k
0th order intigrated rate law is
[A] = -kt +[A]o
0th order half-life
[A]o/2k
as tempature increases
rate increases
as tempature increases what happens to k?
k increases
how do you solve for Ea?
Ea = Ink2/k1(R)/(1/T2-1/T1)
how do you solve for Ink2/k1
Ink2/k1 = -Ea/R(1/T2-1/T1)
in a reaction mechanism the larger the k
the faster the reaction
k2 is larger then
k1
