Question

Consider the reaction

2NO(g) + O2(g) = 2NO2(g)
Suppose that at a particular moment during the reaction nitric oxide
(NO) is reacting at the rate of 0.066 M/s. (a) At what rate is NO2
being formed? (b) At what rate is molecular oxygen reacting?

Answer 1

(a) Rate of formation of NO2 is also 0.066M/s

(b) Rate of reaction of O2 gas is 0.033M/s

Step-by-step explanation:

(a) in one second, according to the equation,

2 moles of NO combines with 2moles of NO2.

Therefore 0.066M NO will still consume 0.066mole NO2.

(b) According to the equation,

2 moles NO consumes 1 mole O2, 0.0666M will consume 0.0333 mole O2
