Question

Rate-Determining Step K12 of 15> A multistep reaction can only occur as fast as its slowest step. Therefore, it is the rate law of the slow step that determines the rate law for the overall reaction. Part A Consider the following multistep reaction: A + B- AB (slow) A + AB A2B (fast) 2A +B A2B (overall) Based on this mechanism, determine the rate law for the overall reaction. Express your answer in standard MasteringChemistry format. For example, if the rate law is k(A] [B2 type k (A 3 (B] 2. View Available Hint(s) Submit Part B Consider the following multistep reaction: C+D CD (fast) CD + D- CD2 (slow) CD2 +D-+CD3 (fast) C+ 3D CD3 (overall)

Explanation / Answer

becouse in the part A Formation of AB throught the reaction A+B=AB ia a slow step and the slow step determine the rate of overall reaction . so the rate law for part A is given as

Part A Rate Law =k*A*B  

also in part B formation of CD2 BY CD+D=CD2 is slow step which is determine the rate law foe overall reaction of part B sDo rate law is given as

Rate Law =k*C*D^2
