Homework Help: Chemistry

Posted by Jamie on Sunday, May 16, 2010 at 2:59pm.

Just a few questions about rates of reaction.

A) Why are the units for average and instantaneous rates the same?
-because they are both measures of how quickly a reaction is occuring per unit time

B) For a given set of data, two students determined different average reaction rates. If neither student made an error in the calculations, account for the difference in their reaction rates.

C) Propose a reason for the difference in instantaneous rates at differnet points throughout a reaction.

D)When chemists compare the rates of reactions carried out under different conditions, they often compare the rates near the beginning of the reactions. What advantages do you see in this practise. Hint: think slow reactions.
-saves time
