Integrated Rate Law
15. Chemical Kinetics / Integrated Rate Law / Problem 1

According to the reaction 2 NO(g) → N2(g) + O2(g) , nitrogen monoxide (NO) decomposes at 400 °C. Three graphs were created when the concentration of NO was tracked throughout time: 

Graph showing the concentration of NO decreasing over time during the reaction.

Graph depicting the natural logarithm of NO concentration decreasing over time.

Graph illustrating the reciprocal of NO concentration increasing over time.

What is the rate law for the reaction?
