Effect of molecular weight in the rate of diffusion

Ombid Group 3 Sec. The Brownian gesture, recognized for the first clip by the Scots phytologist Robert Brown, was elucidated decennaries subsequently by Albert Einstein, the celebrated German-Jewish physicist. A white ring of smoke formed inside the glass tube nearer to the HCl.

A inaccurate measurements, B unequal amount of solutions put and C for not dropping the solutions all at the same time. This means that the higher the molecular weight, the slower the rate of diffusion and frailty versa.

Full Answer Diffusion refers to the net arbitrary motion of particles from areas of higher concentration to areas of lower concentration until the concentration gradient reaches an equilibrium state. Such factors include temperature or presence of energy, the distance, the barriers, the concentrations and many more.

New hampshire4OH with the lower molecular weight at When passing by a bakery shop, we can directly smell the aroma of the bread and when going to a perfume store, we can soon smell the fragrance of the perfume. Biology 1 Laboratory Manual: The observation revealed that the greater molecular weight means a lower diameter of covered area.

How does molecular weight affect the rate of diffusion?

At a given temperature, a substance having lower molecular weight tends to move faster than a substance having higher molecular weight. The total distance was calculated by adding the distances of the two substances from each initial point. The same is true for pressure and temperature. Thus, the higher the molecular weight, the slower the rate of diffusion.

A graph showing the molecular weights of potassium permanganate, potassium dichromate and methylene blue and their corresponding average rate of diffusion.

Molecules in Motion Six physical and environmental conditions govern the rate of diffusion. Table 3 Table 3 shows the trend of rate of diffusion of each solution.

Inhis work was subsequently published in the Philosophical Magazine. Water Agar-Gel Set-up To measure the rate of diffusion with the factors of molecular weight and time the water agar-gel set-up was used.

During the process of diffusion, the substance moves from an area of higher concentration to an area of lower concentration. Such process is known to be the diffusion Myers, Oldham and Tocci, Unequal amount of solution for the three wells, uncoordinated way of putting the solutions into the wells and some inside and outside factors played a big role in proving the hypothesis to be right.

All computed values were tabulated. The measured diameter was recorded for zero minute. That is, as the time increases, the partial rate of diffusion of all the substances decreases.

The Effect of Molecular Weights on the Rate of Diffusion Sharmaine S. Bungabong Group 1 Sec. Y-7L August 11, A scientific paper submitted in partial fulfilment of the requirements in General Biology I Laboratory under Prof. Cristina Dorado, 1st sem., ABSTRACT The effect of molecular.

The experiment was conducted at Room C, Institute of Biological Sciences, University of the Philippines-Los Banos College, Laguna, August 4, MATERIALS and METHODS To determine the effect of molecular weight on the rate off diffusion of a liquid an agar-water gel in a petri dish was used as a medium with three wells.

The Effect of Molecular Weight on the Rate of Diffusion of Potassium permanganate (KMNO4), Potassium dichromate (K2Cr2O7) and Methylene blue ยน ABSTRACT The effect of molecular weight on the rate of diffusion was determined using the Agar-water Gel Test.

At equal temperatures, lighter particles will diffuse more rapidly than heavier particles. Diffusion is the movement of particles from where they are more concentrated to where they are less concentrated. The average kinetic energy of a particle (KE) gives us the temperature of a substance. KE = 1/2mv^2 If we have two gases (A and B) with gas A.

The effect of molecular weight in the rate of diffusion was determined by placing potassium permanganate (KMnO4), potassium dichromate (K2Cr2O7), and methylene blue in a petri dish of agar-water gel with three wells.
