# Interpreting Kinetics Data Question Watch

Announcements
1. Hi,

I'm trying to do a homework sheet and I don't entirely understand the question, I'm on Q1 part 1. My teacher thought it might have been a mistake on their part at first but now looking at it he said "consider the volume and how that affects the concentration" but I still can't work it out.

The pictures attached show the data and the questions. Any help would be greatly appreciated.

the concentration of each reagent is the number of moles of that reagent divided by the total volume of the mixture.Mixture A has a total volume of 400cm^3Mixture B has a total volume of 200cm^3

hopefully then you can see that if (for example) mixture A has 20cm^3 of a reagent and mixture B has 10cm^3 of that reagent, then the concentration of that reagent is the same in both mixtures (twice as much reagent in twice as much volume is the same concentration).

Hope that helps

Oh I see! Thank you so much that's really helpful!
