The conservation reserve is probably the most important federal program for promoting  conservation on private lands. Which department and agency of the U.S. government delivers this program and how does it work? 

The following is the overall reaction that occurs when HCl is mixed with I-C(CH3)3. (In this case, the – between I and C is for easy-reading purposes only).   HCl(aq) + I-C(CH3)3(aq) -> HI(aq) + Cl-C(CH3)3(aq)   When an initial rate study is taken for this reaction, the following data are obtained.   Initial Rate 1.784 M/s 0.200 M 0.200 M 0.100 M 0.0500 M 0.892 M/s 0.400 M 0.200 M 0.100 M 0.100 M 0.446 M/s 0.400 M 0.100 M 0.100 M 0.100 M 2.676 M/s 0.300 M 0.300 M 0.100 M 0.0500 M 2.379 M/s 0.100 M 0.400 M 0.200 M 0.150 M   a.) What are the orders of all the species studied? Create a rate law from those data (including a rate constant). b.) Using your answers from A, propose a mechanism that would give the the observed rate law. How realistic your reactions are is unimportant for this question, only that it would yield a rate law that matches the observed data and overall reaction.
