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!

What is hyperbole in the story "The Gift of the Magi" by O. Henry?

The most obvious use of hyperbole in "The Gift of the Magi" occurs when the narrator describes Della's and Jim's evaluations of their two treasures—her long, luxuriant hair and his gold watch. Had the Queen of Sheba lived in the flat across the airshaft, Della would have let her hair hang out the window some day to dry just to depreciate Her Majesty's jewels and gifts. Had King Solomon been the janitor, with all his...

How can I analyze Moon and Six Pence by Somerset Maugham?

In "Moon and Sixpence," loosely based on the life of Paul Gaugin, Maugham presents a study of the tension between the "civilized" life of 19th century Europe, and the lead character's desire to throw off the shackles of bourgeois life. Charles Strickland is a middle-aged English stockbroker with a wife and family. By abandoning his domestic life, Strickland commits what many in European society would consider a gross betrayal of one of the foundations of...

What are some literary devices in Macbeth, Act V, Scene 1?

Act V, Scene i of Macbeth certainly continues the imagery that is prevalent in the play with its phantasmagoric realm, as in this scene a succession of things are seen or imagined by Lady Macbeth. Imagery - The representation of sensory experience Lady Macbeth imagines that she sees bloody spots (visual imagery) on the stairs; she also smells blood (olfactory imagery): Here's the smell of the blood still. All the perfumes of Arabia will not...
