Part A

The reactant concentration in a zero-order reaction was 0.100 M after 170 s and 3.00×10-2 M after 380 s . What is the rate constant for this reaction?

Part B

What was the initial reactant concentration for the reaction described in Part A?

Part C

The reactant concentration in a first-order reaction was 6.10×10-2 M after 40.0 s and 4.10×10-3 M after 70.0 s . What is the rate constant for this reaction?

Part D

The reactant concentration in a second-order reaction was 0.260 M after 295 s and 7.70×10-2 M after 860 s . What is the rate constant for this reaction?
