A chemist studies a chemical reaction whose rate law depends only on the concentration of a reactant "A." although she doesn't know if the reaction is first order or second order in A. She presents the following data for you. 1) The plot of In [A] versus time In[A] time 2) The initial concentration of A is 1.5 M. 3) 40.0% of A reacts in 22 seconds. Based on this information, determine the value of the rate constant for this reaction.

The reaction: NO (g) + O3 (g) —> NO2 (g) + O2 (g) Is thought to be a second-order reaction with respect to O3. You start with [O3] = 0.250 M. After 125 s you find that the [O3] has dropped to 0.145 M. A) Assuming the reaction is second order, determine the value and units of the rate constant. B) Determine the half-life of the reaction. C) Calculate [O3] after 195 seconds.
