Final answer:
To determine the reaction order and rate equation, we can analyze the given data and plot appropriate graphs. By comparing the initial rates for different experiments, we can identify the reaction order. Using the integrated rate law, we can calculate the rate constant for the first-order reaction.
Step-by-step explanation:
To determine the order of the reaction and the rate equation, we need to analyze the given data and plot the appropriate graphs. From the data, we can calculate the initial rates for different combinations of reactant concentrations. By comparing the initial rates for different experiments, we can identify the reaction order.
- Plotting the ln([H₂O₂]) versus time graph can help us determine if the reaction follows a first-order rate law. If the graph is linear, the reaction is first-order.
- Next, we can determine the rate constant, k, by using the integrated rate law for the first-order reaction: ln([H₂O₂]) = -kt + ln([H₂O₂]₀), where [H₂O₂]₀ is the initial concentration of H₂O₂ and k is the rate constant.
By completing these steps, we can determine the order of the reaction (first-order) and the rate equation (ln([H₂O₂]) = -kt + ln([H₂O₂]₀)).
