Question: Reaction Order And Rate Laws Peter Jeschofnig, Ph.D. Version 42-0195-00-01 Lab Report Assistant This Document Is Not Meant To Be A Substitute For A Formal Laboratory Report. The Lab Report Assistant Is Simply A Summary Of The Experiment’s Questions, Diagrams If Needed, And Data Tables That Should Be Addressed In A Formal Lab Report.
Determining the Rate Law from Experimental Data. In order to experimentally determine a rate law, a series of experiments must be performed with various starting concentrations of reactants. The initial rate law is then measured for each of the reactions. Consider the reaction between nitrogen monoxide gas and hydrogen gas to form nitrogen gas.

Explanation:. When determining the rate law for a reaction, you need to determine the order for each reactant in the reaction. This can only be accomplished by performing an experiment where different trials show how the initial reaction rate changes based on the initial concentrations of the reactants.
The Kinetics of the Iodine Clock Reaction Pre-lab Assignment Before coming to lab: x Read the lab thoroughly. x Answer the pre-lab questions that appear at the end of this lab exercise. The questions should be answered on a separate (new) page of your lab notebook. Be sure to show all work, round answers, and include units on all answers. Background information can be found in Chapter 14.
Given the following two reactions and their experimentally determined differential rate laws: determine the units of the rate constant if time is in seconds, determine the reaction order with respect to each reactant, give the overall reaction order, and predict what will happen to the reaction rate when the concentration of the first species in each equation is doubled.
