Consider the reaction, 2N O 4NO O . -> In the reaction NO2 is being formed at the rate of 0.0125 mol L–1 s–1. What is the rate of reaction at this time?

2 5 2 2 2 4 N O NO O -> Rate of formation of 2 0.0125 NO mole L-1 s-1 Rate of reaction = 1 4 xRate of formation of 2 NO 1 0.0125 4 x mol L-1 s-1 0.0031 mol L-1 s-1
