Question

Part A

The reactant concentration in a zero-order reaction was 6.00×10^?2M after 105 s and 4.00×10^?2M after 335 s . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

Part B

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

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

Part C

The reactant concentration in a first-order reaction was 6.70×10^?2M after 35.0 s and 9.10×10^?3M after 70.0 s . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

Part D

The reactant concentration in a second-order reaction was 0.310 M after 120 s and 1.00×10^?2M after 835 s . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.
