### Understanding Reaction Mechanisms and Rate LawsIn chemical kinetics, understanding the mechanisms and deriving the rate laws of reactions is crucial to predict how different factors influence reaction rates. Below, we explore the rate laws for two different proposed mechanisms for a reaction involving hydrogen (H₂) and bromine (Br₂) to produce hydrogen bromide (HBr).#### Mechanism II:$$H_2 + Br_2 \xrightarrow{k_2} 2HBr \hspace{5pt} (\text{slow})$$### Exercises**a) Derive the rate law for Mechanism I.***Show all work on paper - use a ^ here to indicate a superscript if necessary.*\[ \boxed{\text{Answer}} \]**b) Derive the rate law for Mechanism II.***Show all work on paper - use a ^ here to indicate a superscript if necessary.*\[ \boxed{\text{Answer}} \]**c) The observed rate law for the reaction is $r = k_{obs}[H_2][Br_2]^{1/2}$.

However, you are requested to derive and analyze the rate laws and mechanisms as described above. Remember to provide detailed steps in your derivations and clearly indicate any assumptions or approximations you make.These exercises are designed to help you understand how different mechanistic steps impact the overall rate law of the reaction and the importance of intermediates in determining reaction kinetics. In-depth knowledge of these aspects is essential for students aiming to master the principles of chemical kinetics. ### Reaction Mechanisms for the Formation of HBrIn addition to filling in the blanks below, show all of your work for this problem on paper for later upload.#### Mechanism I:Two mechanisms have been proposed for the formation of HBr from elemental hydrogen and bromine.
