Question
Can someone please explain to me why this would be 1st order?
The following data for the disproportionation 2 H_2O_2 2 H_2O + O_2 with a soluble Mn^2+ catalyst were adapted from Burke A., Dissertation, University of Florida. The natural log of [H202] is plotted on the y-axis, time is plotted on the x-axis, and the data fit to pretty good straight lines. What is the reaction order with respect to H_2O_2? Please write your answer below the figure caption. Plot of the ln([H_2O_2]) versus time for varying bicarbonate concentration. The 0.20 and 0.30 M bicarbonate reactions are typical of the accelerations noticed for these reactions. Reaction conditions: 0.10 M H_2O_2.4 mu M Mn(II).Explanation / Answer
Ans: 1) The rate of the reaction depends on the concentration of the Reactant.
2) ln(Abs) Vs time gives the straight line in the Graph.
These are some conditions for the First order reaction.
