Question

(Medal & Fan! :>)
Brad and Matt are working in the lab. They noticed that when they mixed two dilute solutions together, the reaction between them happened very slowly. Which of Matt's suggestions would BEST help to increase the rate of this reaction?

Answer 1

A) increase the concentration of both solutions
B) decrease the concentration of both solutions
C) increase the concentration of one of the solutions
D) decrease the concentration of one of the solutions

Answer 2

the rate equation varies jointly with the concentration of the reactants in dilute solutions

what does that suggest to you?

Answer 3

decrease the concentration of one of the solutions

Answer 4

@badsheep no, that will not increase the rate of the reaction!

more molecules of both reactants in solution -> more molecules reacting

for a real life example, imagine a school dance with 1000 adult chaperones, 10 boys, and 10 girls. not much dancing will be happening. if you remove some of the boys, or some of the girls, even less dancing will be happening. adding more boys AND more girls will be the most effective way (given that the number of chaperones will not change) to get more dancing happening.

Answer 5

okay, you have to take "real life" with a grain of NaCl in that example, I suppose :-)

Answer 6

I had already gotten the answer. But, yes thank you so much for responding and describing! I'll be sure to medal and fan you! :) If I have any more questions I'll definitely ask you.

Thanks again!

Answer 7

@whpalmer4 ha ha ok sorry
