Question

If the concentration of a reactant is decreased, will the speed of the reaction increase or decrease? Explain.

I understand that if the concentration of a reactant is INCREASED, the frequency of coliision increases, making the rate of reaction increase. How aboout when the concentration is decreased?

Answer 1

You are correct that increasing the concn increases the rate and for the very reasons you site. Then wouldn't you expect decreasing the concn would have just the opposite effect?

Answer 2

That is my guess, that decreasing the concnetration of a reactant will decrease the rate of the reaction because there is a decrease in the frequency of collisions. Am I right?

Answer 3

Yes, doesn't that make sense to you?

Answer 4

It does, thank you for the help! :)
