2. Which statement regarding the rate determining step is TRUE:
All reactions have a rate determining step Rate determining steps can only be unimolecular The step is usually slow The step is usually fast Overall reaction has to be faster than the rate determining step

3. A differential rate law shows which components of a reaction...
time and concentration volume and pressure ln[concentration] and time rate and time rate and concentration

4. For a 2nd order rate law, the plot of wchich of these gives a straight line:
rate vs. concentration time vs. concentration [A] vs. time ln[A] vs. time 1/[A] vs. time

5. The rate law for reaction A is: rate=k[A]^{2. When [A] was 2.0 molar, the reaction was found to be 3.0x10-3 mol/L*s. Determine the rate constant.}
7.5x10^-4 7.5x10^-3 1.5x10^-3 1.5x10^-4 none of the above
