    hi im doing the catalytic decompisition of hydrogen peroxide. i used manganese oxide as a catlyst and potassium permanganate. my teacher said if i just change the concentration of hydrogen peroxide and measure the rate it will be fine because i can still wokr out the order of hdrogen peroxide. manganese oxide doesnt dissolve into a solution. iknow i can't make a rate equation. another aim was to see how the tempreture of pottassium permangante and hydrogen peroxide effects the rate of decompistion. is it true i need a rate equation and different concentrations to work out Arrhenius equations.

    You accidentally put this in the English Study Help Forum.

    I have thus moved it into the Chemistry Study Help Forum instead.

    Hopefully you'll get some help soon!
