2. For a first-order reaction, reaction rate and concentration are
directly proportional inversely proportional independent cannot be determined none of the above
3. A 1.2 molar solution A has a rate constant of 3.4 L/ mol*s. Determine its half-life if its rate law is second-order.
.24 .245 4.08 4.1 1.0
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. First-order reaction A has a half-life of 5.0 days. Find its rate constant.
