General Chemistry 2 - Quiz - Chemical Kinetics: Rate Laws
What is the rate of the following reaction: 2A + B → C?
A is a reagent and its stochiometric coefficient is 2. Reaction rate of a reagent:
α = stochiometric coefficient
[reagent] = concentration of the reagent (in mol.L-1)
What is the overall order of a reaction with a rate = k [A]2 [B]?
The overall order of reaction is the sum of the orders of reaction of all the reactants
What are the units of the constant k in the rate of reaction = k [A]2 [B] (concentration in mol.L-1) ?
The rate of reaction is in mol.L-1.s-1 and [A]2 [B] is in mol3.L-3 ⇒ k is in mol-2.L2.s-1
What is correct concerning the half-time of a first-order reaction?
For a first-order reaction:
What is correct concerning the half-time of a second-order reaction?
For a second-order reaction:
What is the relationship between [A] and t for a first-order reaction?
For a first-order reaction: = k [A]
After integrating: ln [A] = ln [A]0 - kt ⇒ = e-kt
