to find k

Postby Ekayana Sethi 2K » Thu Mar 08, 2018 7:54 pm

To find the k from experimental data do we have to find the k from each experiment and then find its average? Or just any one experiment to find k?

I think that normally, the question will have the data be in such a way that k will generally be the same throughout several experiments with different concentrations. I'm guessing that if there is a noticeable difference in k values from each experiment, we might average them out.

From my knowledge and the homework problems, k seems to be the same throughout experimental data regardless of the concentrations.

In problems where the experimental results are given, the k value calculated should be the same for each trial, but in actual experimentation the results will not be as accurate and precise so you would average them.

The r (rate constant) you find from a data table containing concentrations and rate, will be the same for all entries, that is because concentration does not affect the rate constant, only the rate.
