Rate equations and mechanisms

What you'll learn

1. 1

   A rate equation links the speed of a reaction to the concentrations of the reactants.

2. 2

   If a reaction is first order with respect to A, what happens to the rate if [A] doubles?

3. 3

   Let's work out the rate equation from this data:

4. 4

   Drag the concentration values to see how rate changes for a reaction that is first order in A and second order in B.

5. 5

   For a rate = k[A]²[B], if [A] doubles and [B] stays the same, the rate:

6. 6

   A mechanism must match the rate equation. Let's check this one:

7. 7

   If the slow step of a mechanism is A + B → C, what is the rate equation?
