    Doing hydrogen peroxide with potassium iodide and H+ ions with starch.

    and I have a value for the activation enthalpy but is there a standard activation enthalpy at room temperature to compare with?

    Just wondering as to compare my value with it.


    Thanks!

    I'm doing propanone and iodine solution with H+ catalyst. My activation enthalpy was 62.15, and a friends was 61.1.
    This might not be very helpful, i've tried googling mine and haven't found much.
    Have you got k values in your rate equation?
    I'm unsure whether to do concentration of my H+ (1mol), or concentration in the solution, I used 10cm3, so that would be 0.01mol?
