Question

Determine the rate law, the value of the overall reaction order, and the value of the rate constant, k, from the following data, which was collected at room temperature?

Answer 1

The determination of the rate law, overall reaction order, and rate constant (k) involve analyzing experimental data to see how concentration changes affect reaction rates and calculating k using the rate law with correct units.

Step-by-step explanation:

To determine the rate law, the overall reaction order, and the rate constant (k), from experimental data, one typically follows these steps:

• Compare changes in reaction rates with changes in reactant concentrations to determine the order of the reaction with respect to each reactant.
• Use the determined reaction orders to write the rate law for the reaction.
• Calculate the rate constant (k) using the rate law and data from one of the trials, ensuring units are appropriate.
• If additional calculations are necessary, such as finding remaining concentrations of reactants, apply the rate law with known quantities.

Without the actual numerical data from the experiment, it is not possible to provide specific values for the reaction orders or the rate constant. However, the steps described can be applied to any set of data to determine these values.

Note: It is critical that units of k are compatible with the experimentally measured rate and concentration units. For example, if concentration units are mol³/L³, then k should have units of mol-2 L²/s to ensure that the reaction rate comes out as mol/L/s.
