I need to find the order of a reaction with respect to the reactants.
I set up my equation like this:
5.33e-2 M / 2.66e-2M = 1.03e-2 / 1.93e-3
I did the concentrations equal to the rates. I am just not sure what the units for rate should be.
2.00 = 5.33^m
Did I set this up correctly to find the order or would the order just be 2 from 5.33e-2M / 2.66e-2M ??
Thank you for your help!!
Diregard question.
To determine the order of a reaction with respect to the reactants, you need to compare the concentrations of reactants to the corresponding rates of the reaction. It seems like you have set up the ratio of concentrations correctly, but there are a few issues with the calculations and interpretation.
First, let's clarify the setup of the equation. The reaction rate should be expressed as the change in concentration of the reactants or products per unit time. Typically, the unit for reaction rate is M/s (moles per liter per second). So, for the ratio of concentrations, you should have:
(rate of reactant A) / (rate of reactant B) = (concentration of reactant A) / (concentration of reactant B)
Also, note that the equation you wrote, 2.00 = 5.33^m, is incorrect. This equation does not represent the ratio of concentrations or rates.
To determine the order with respect to the reactants, you need to perform experiments where you vary the concentration of one reactant while keeping others constant. By measuring how the reaction rate changes with varying concentrations, you can determine the order of the reaction.
For example, if you carry out experiments where the concentration of reactant A is varied while the concentration of reactant B is kept constant, and you observe that doubling the concentration of A doubles the rate of the reaction, you can conclude that the reaction is first order with respect to A.
Similarly, if you find that doubling the concentration of both reactants A and B quadruples the rate of the reaction, you can conclude that the reaction is second order overall (first order with respect to each reactant).
In summary, you cannot determine the order of the reaction solely based on the given concentrations. You need to conduct experiments and analyze how the rate changes with varying concentrations to determine the order of the reaction with respect to each reactant.
