rate law

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
