Biology - URGENT Enzyme Lab

Did a catalase producing hydrogen peroxide lab, used manganese dioxide, fresh frozen liver, potato, ice, fine clean sand, etc. Basically just added hydrogen peroxide to the catalysts under diff conditions and stuff.

Just don't get this question which is : how do you account for the differences in the rates?

other question is what is the effect of temp? and does size of particle matter for rate of enzyme?

also dogs body temp is forty degrees, so i don't know if i would have gotten diff results if i used piece of dog liver for this lab.
