Reaction Rates Lab Report

  1. Nov 27, 2012 #1
    The reaction I did for the lab is:
    H2SO4 + Mg --> MgSO4 + H2

    In my graph, there displays the two variables - the concentration of sulfuric acid and the average rate of reaction in direct proportion. How do I explain the trend?

    I know I can explain this qualitatively using collision theory, but to explain why they are in direct proportion requires the rate law from what I know.

    Since the graph shows a linear relationship, the experiments show that the order of reaction with respect to sulfuric acid is 1. I think I need to explain this by finding the rate determining step of this reaction and putting the coefficients as the powers, but I do not know the reaction mechanism. Can anyone help me out here and explain why it is this reaction mechanism and which is the rate determining step?
