Question

Part A:

The reactant concentration in a zero-order reaction was 6.00×10−2 M after 185 s and 3.00×10−2 M after 330 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.

k0th = 2.07×10⁻⁴ Ms

(I did this one already)

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.

[A]0 = ______

Part C:

The reactant concentration in a first-order reaction was 7.70×10−2 M after 25.0 s and 6.20×10−3 M after 100 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.

k1st = ______

Part D:

The reactant concentration in a second-order reaction was 0.110 M after 110 s and 2.00×10−2 M after 795 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.

k2nd = ______
