Chemical Kinetics Flashcards
What is a sign for reaction rate
V
What is formula for reactiom rate for reversibke reactions
v=-1/a ×d[A]/dt
What is reaction rate equal to at equilibrium state
0
What is kinetic law
A function v of onstantenuois concentrations of the species involved in the reaction
What is formula for v in reversible reactions
v=k[A]^(n)[B]^(m)
What is is overall order
p=n+m
What are simplest kinetic laws
v=k[A]
v=k’[A]²
v=k”[A][B]
What is formula for first order kinetic process
[A]=[A]0exp(-kt)
What us formula for half lifenof 1st order process
t(1/2)=ln2/k
What is formula for 2nd order kinetic process
1/[A]=1/[A]0 +kt
Qhat is hald life of 2nd order process
t(1/2)=1/k[A]0
Qhat are global second order formula
1)[A]0=[B]0=>[A]=[B]
2)[A]0«[B]0=>[B]0 const
V=k’[A]
[A]/[A]0exp(-k’t)
What is half time of global 2nd order
t(1/2)=ln2/k[B]0
What is formula for concentration of products
[P]=[A]0-[A]
