Name:
The half-life for the reaction was studied with equal initial amounts of NO and at a series of different initial pressures ( ):
The rate is known to only depend on the concentrations of the two reactants. Find the overall order of the reaction.
Note: Drawing a graph is optional.
For a reaction of general order, .
If equal amounts of NO and are used, and since they are used in a 1:1 stoichiometry, the rate law reduces to a simple form. Moreover, since concentrations and pressures are proportional, they can be used interchangeably in this kind of problem.
