Question 2 (2 points) The radioactive decay of an isotope was measured for 1 week. The kinetics were modeled using a first order integrated rate law plot, such that In[amount of radioactive isotope remaining] was plotted on the y-axis and time was plotted on the x-axis. The data set was modeling using a linear equation, y=-0.542-1.92. In blank # 1, determine the rate constant for the...
