Answer to Question #208161 in General Chemistry for mel

Question

The decomposition of N₂O₅ can be described by the equation

2N₂O₅(soln) ------> 4NO₂(soln) + O₂(g)

consider the data in the table for the reaction at 45*C in carbon tetrachloride solution.

Table:

t(s) / [N₂O₅] (M)

0 / 1.824

205 / 1.603

406 / 1.413

805 / 1.099

Given the data, calculate the average rate of reaction for each successive time interval.

what is the average rate of reaction for the time interval 0s to 205s?

what is the average rate of reaction for the time interval 205s to 406s?

what is the average rate of reaction for the time interval 406s to 805s?
