Hello! A table of points for an experiment is given. there areactually3 more points, but I think the concept is more what I'mconfused on, so I don't think it matter how many trials thereexist. time (s) [NOBr] (M) 0.00 0.0100 2.00 0.0071 4.00 0.0055 I need to determine the avg. rate over the entire expertiment,but I'm not sure I would do that. I'd also need to determine theavg. rate between 2 and 4 sec, which I think is doneas: (.0055-0.0071)/(4-2). Thanks ahead of time. Hello!

Explanation / Answer

Average rate = Change in concentration of reactant /Time elapsed So average rate over the entire experiment = 0.0055M - 0.0100M/ ( 4 -0)s       average rate between 2and 4seconds = 0.0055M - 0.0071M / ( 4 - 2)s
