Question
Consider the decomposition of dinitrogen pentoxide shown above. In order to determine the rate of this reaction, we can measure the concentration of N2O5 at various time intervals throughout the reaction. The data and graph of [N2O5] verses time are shown below.
(A)What is the average rate of reaction for N2O5in the first 400 seconds?NOTE:The sign is important!
_________ M/sec
(B)What is the average rate of the reaction for N2O5between 600 and 1200 seconds?
_________ M/sec
Explanation / Answer
A) avg rate= (- change in A)/(change in time) --> -(.78-1.00)/(400-0) = +.00055 M/sec B) same thing as the guy ^ but the number is POSITIVE
