The Rate of a Chemical Equation/Chemical Kinetics Lab?

Posted on 2015-11-28 07:51:00 in Chemistry by MICHAEL BRUSH

Firstly, I appreciate anyone and everyone who takes the time to read my questions and answer them. I truly do thank you for your time.

Now, I've been trying to wrap my head around a chemistry lab. The calculations portion of my lab asks a few questions most of which I'm not sure I understand either what they're asking or how to perform the equations.

1) How to find the concentration of acetic acid where there is a 7.5ml amount of acetic acid within a 15ml solution? 3.0ml of the 7.3ml amount is within a 0.5 M buffer along with another NaC2H3O2 and the rest (4.5ml) is 0.3 M.

2) The effects of temperature in a reaction will be calculated using the reaction rate ratio of:

rate5/rate1 = Delta(t1)/Delta(t5) = kT1/kT5

Delta's 1 and 5 are the values of the experiment, however I am unsure what value they are wanting in particular, whether it be temperate or time? Also, what does the k and T signify?
