Part A

The rate constant for a certain reaction is k = 1.70×10−3 s−1 . If the initial reactant concentration was 0.300 M, what will the concentration be after 8.00 minutes?

Part B

A zero-order reaction has a constant rate of 1.80×10−4M/s. If after 60.0 seconds the concentration has dropped to 5.00×10−2M, what was the initial concentration?

Learning Goal: To understand how to use integrated rate laws to solve for concentration. A car starts at mile marker 145 on a highway and drives at 55 mi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours? This problem can easily be solved by calculating how far the car travels and subtracting that distance from the starting marker of 145.

Part A: The rate constant for a certain reaction is k = 3.10×10−3 s−1 . If the initial reactant concentration was 0.750 M, what will the concentration be after 8.00 minutes? Part B: A zero-order reaction has a constant rate of 2.80×10−4 M/s. If after 50.0 seconds the concentration has dropped to 1.50×10−2 M, what was the initial concentration?
