Question

20.799 atm 10 100 150 200 250 300 seconds created Is NO being created or destroyed by the chemical destroyed reaction? neither created nor destroyed If NO2 is being created or destroyed, what is the rate at which it is being created or destroyed 110 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol If NO2 is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 110 seconds of the reaction?

Explanation / Answer

Part a

From the given graph

The pressure of NO2 is decreasing continuously so NO2 is being destroyed by the chemical reaction

Part b

Rate of reaction = - 9 atm / 110s = - 0.0818 atm/s

= - 8.18*10^-2 atm/s

Part C

Average rate = - ( 9 - 0)atm / (110 - 0)s

= - 8.18*10^-2 atm/s
