What is the rate expression for the reaction A + 2B → Products?
Think about the coefficients of reactants.
If doubling the concentration of a reactant doesn’t change the rate, what is the order with respect to that reactant?
Consider how the rate behaves when reactant concentration changes.
What does the rate expression show?
Focus on the role of concentration in determining the rate.
True or False: The order of reaction can be determined from the stoichiometric coefficients alone.
Think about how order and coefficients relate.
Given the reaction data for A + 2B → Products: Experiment 1 with Rate = 3.0 x 10^-3 at [A]=0.1 and [B]=0.2. Experiment 2 with Rate = 6.0 x 10^-3 at [A]=0.2 and [B]=0.2. Determine the orders with respect to A and B and write the rate expression.
Compare rates while keeping one reactant constant.
Solve for k using the following data: Rate = 4.0 x 10^-3 at [A]=0.1 and [B]=0.3. Calculate the rate constant for this reaction.
Ensure you apply the correct units when calculating k.
