this is a lab i am working on and this is what is says:

Question

Solution A is mixed with water to produce solutions of varying concentration. These altered concentrations of solution A is added to a set amount of solution B and the reaction times are noted when the solutions are mixed.

Then i am given a table of results.

What i am supposed to do is Calculate the concentration of solution A in each reaction.

How do I do this???

Answer 1

reaction time is dependent on concentration, see http://www.science.uwaterloo.ca/~cchieh/cact/c123/coneffec.html

So you have to know the balanced reaction to figure the rate equation as in the link. It could be linear, a second order rate change, or ...
