The overall reactions and rate laws for several reactions are given below. Which one of these represents an elementary step?

A) A + 2B → P rate = k[A]2

B) A + 2B → P rate = k[A][B]

c) 2A → P rate = k[A]

D)A + B + C → P rate = k[A][C]

E) A + B → P rate = k[A][B]

Expert Solution

If the rate law can be derived from the given reaction, then the given reaction can be said to be elementary reaction

E is elementary reaction because rate law from reaction will be

rate = k [A] [B]

which is same as given rate law

Answer: E

for A, rate law from given reaction is

rate= k [A] [B]^2 which do not match given rate law

for B, rate law from given reaction is

rate= k [A] [B]^2 which do not match given rate law

for C, rate law from given reaction is

rate= k [A]^2 which do not match given rate law

for D, rate law from given reaction is

rate= k [A] [B] [C] which do not match given rate law

For reactions governed by the rate laws below, the concentration of reactant A is doubled while the concentration of reactant B is halved. Match the rate law to the change in rate of reaction that would be observed. (does the rate of the reaction double, decrease by half, quadruple, or is there no change?) Rate = k[A][B] Rate = k[A]^2[B]0 Rate = k[A][B^]2 Rate = k[A]^3[B]^2
