What is the effect of concentration on the rate of diffusion? (the rate of concentration of a substance not the concentration gradient)

I am a little uncertain about what you mean by the part of your question in parentheses, specifically 'the rate of concentration of a substance'. This seems to imply that you are measuring the rate at which a substance is becoming concentrated. This is still just diffusion because during diffusion a substance is moving from areas of high concentration to areas of low concentration, so by measuring the rate at which a substance is becoming...

I am a little uncertain about what you mean by the part of your question in parentheses, specifically 'the rate of concentration of a substance'. This seems to imply that you are measuring the rate at which a substance is becoming concentrated. This is still just diffusion because during diffusion a substance is moving from areas of high concentration to areas of low concentration, so by measuring the rate at which a substance is becoming concentrated in the area of low concentration, you are measuring the rate of diffusion.


Back to your question of how concentration affects the rate of diffusion. The higher the concentration of a substance in relation to its surroundings, the higher the rate of diffusion. For example, diffusion is constantly occurring between your cells and your blood stream, exchanging oxygen and carbon dioxide. During times of intense activity, the cells produce higher amounts of carbon dioxide so the concentration of carbon dioxide inside the cell is higher than normal. Diffusion of carbon dioxide from the cell to the blood stream will occur at a higher rate than when the concentration of carbon dioxide is at more normal levels.


I hope this helps!

How and why does James Gatz become Jay Gatsby? Describe the young Gatsby/Gatz.

James Gatz, a poor Midwestern boy of probable Jewish lineage, becomes Jay Gatsby, a presumed WASP and wealthy socialite, when he moves to New York City and acquires his fortune. It is wealth that has allowed Gatz to transform himself into Gatsby. However, those who know his background (e.g., Daisy and Tom Buchanan) never allow him to forget that he is nouveau riche -- that is, an upstart who has just recently made his fortune,...

It is wealth that has allowed Gatz to transform himself into Gatsby. However, those who know his background (e.g., Daisy and Tom Buchanan) never allow him to forget that he is nouveau riche -- that is, an upstart who has just recently made his fortune, whereas they arose from well-to-do families. Gatz became Gatsby through determination and discipline. At the end of the novel, the narr...

What gift did Della buy for Jim and why in "The Gift of the Magi" by O. Henry?

Della buys Jim a watch fob because his watch is his most prized possession. Della and Jim Young do not have much money. Despite this, Della really wants to buy Jim a good Christmas present. She is even willing to sell her hair to get him a nice gift. This is ironic because we learn Della and Jim both highly prize her hair. Now, there were two possessions of the James Dillingham Youngs in which... Della buys Jim a watch fob because his watch is his most prized possession. Della and Jim Young do not have much money. Despite this, Della really wants to buy Jim a good Christmas present. She is even willing to sell her hair to get him a nice gift. This is ironic because we learn Della and Jim both highly prize her hair. Now, there were two possessions of the James Dillingham Youngs in which they both took a mighty pride. One was Jim's gold watch that had been his father's and his grandfather's. The other was Della's hair.  Della is still willing to sell her hair so she can b...

Explain and discuss how the definitions of freedom change for the nation, for the freedmen and for southern whites after the Civil War.

After the Civil War, the definition of freedom changed in the nation, as slavery was ended with the 13th Amendment to the Constitution in 1865. The practice of slavery was disallowed, but definition of the freedom that would take its place was a subject of controversy, ongoing debate, and even violence in the decades to come.  For freedmen, freedom often meant reconciling with their families, who were broken up by slavery; choosing which church to...
