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], what is the overall reaction order?
First order
Second order
Third order
Zero order
2. Which of the following plots is linear for a first-order reaction?
[A] vs. time
ln[A] vs. time
1/[A] vs. time
Rate vs. [A]
3. The of a reaction is determined experimentally and cannot be deduced from the stoichiometry of the balanced chemical equation.
4. For a zero-order reaction, the rate of reaction is of the concentration of the reactants.
5. Explain the difference between reaction order and molecularity.
6. How can the order of a reaction with respect to a specific reactant be determined from experimental data?
Match the integrated rate law plot with its corresponding reaction order.
7. Plot of [A] vs. time is linear
a. First-order reaction
8. Plot of ln[A] vs. time is linear
b. Second-order reaction
9. Plot of 1/[A] vs. time is linear
c. Zero-order reaction
10. Consider the decomposition of N₂O₅ at a certain temperature:
2 N₂O₅(g) → 4 NO₂(g) + O₂(g)
The following data were obtained:
Time (s) | [N₂O₅] (M)
0 | 0.100
100 | 0.070
200 | 0.049
300 | 0.034
Determine the order of the reaction with respect to N₂O₅ and calculate the rate constant (k).
