louise crushed some rhubarb stalk she crushed an equal mass of rhubarb leaves. she added them separately to equal volumes of potassium manganate and measured the time taken for the colour to change. explain why the rhubarb leaves changed the colour of the potassium manganate in a shorter time than the rhubarb stalk?
