What does a rate equation describe?

Relationship between concentration & reaction rate

What are orders of reaction?

Powers to which concentrations are raised

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], what is the order with respect to B\text{B}?

2

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], what is the order with respect to C\text{C}?

0

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], what is the overall order of reaction?

3

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], by what factor does rate increase when [B][\text{B}] is doubled?

4

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], by what factor does rate increase when [D][\text{D}] is doubled?

2

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], what happens to the rate when [C][\text{C}] is doubled?

No effect on the rate

For Rate=k[B]2[D]\text{Rate} = k[\text{B}]^2[\text{D}], by what factor does rate increase when [B][\text{B}], [C][\text{C}], and [D][\text{D}] are all doubled?

8

What is one reason for deriving rate equations from experimental data?

To identify which reactants influence rate
