Kinetics (2)

Question 1

In a reversible unimolecular reaction from A to B, what is the average lifetime of a molecule in state A and state B?

Answer 1

-state A = 1/K1
-state B = 1/K2

Question 2

In a reversible unimolecular reaction, what is the rate at which molecules go from A to B and from B to A?

Answer 2

-A to B = K1[A]
-B to A = K2[B]

Question 3

In a reversible unimolecular reaction, how do you calculate the overall formation of B?

Answer 3

K1[A] - K2[B]

Question 4

In a reversible unimolecular reaction, what is the equation to show the rates are equal each other and how can this be rearranged to form an equation for Keq?

Answer 4

-K1[A]eq = K2[B]eq
-Keq = [B]eq / [A]eq
-Keq = K1 / K2
