the initial slope of the curve is steepest and this occur when small pieces of marble are used and is due to a small surface area of reactant
the occur when large pieces of marble are used and is due to a small surface area of reactant
the initial slope of the curve is steepest and this occurs when small pieces of marble are used and is due to a large surface area of reactant
the initial slope of the curve is steepest and this occur when large surface area of reactant
the initial slope of the curve is least steep and this occur when small pieces of marble are used and is due to the increased surface area of the reactant
