Read each question carefully and provide detailed answers. Show all your work for calculations.
1. For a reaction A + B → C, if the rate law is Rate = k[A]^2[B]^0, what is the overall order of the reaction?
First order
Second order
Zero order
Third order
2. The half-life of a first-order reaction is independent of the initial concentration of the reactant. Is this statement true or false?
True
False
3. The is a mathematical expression that relates the rate of a reaction to the concentrations of reactants.
4. For a zero-order reaction, the rate constant (k) has units of .
5. Explain the difference between the molecularity of a reaction and the order of a reaction.
6. How can experimental data be used to determine the order of a reaction with respect to a specific reactant?
7. The decomposition of N2O5(g) is a first-order reaction with a rate constant of 6.2 x 10^-4 s^-1 at a certain temperature. If the initial concentration of N2O5 is 0.50 M, calculate the concentration of N2O5 after 30 minutes.
