NO(s) and O2(s) react as follows: 2NO(s)+O2(s)2NO2(s) It has been determined experimentally that the rate law of the above reaction is second-order in NO and first-order in O2 : The following particle-level pictures represent mixtures of NO(s) (red and blue particles) and O2 (s) (pure red particles). (1) (2) (3) Which mixture has the fastest instantaneous rate of reaction? (1) (2) (3) (1) and (2) are tied for fastest (2) and (3) are tied for fastest (1) and (3) are tied for fastest All three mixtures have the same instantaneous rate of reiction
