The reaction of NO and O₂ produces NO₂. 2 NO(g) + O₂(g) → 2 NO₂(g)
The reaction is second-order with respect to NO(g) and first-order with respect to O₂(g) .At a given temperature,the rate constant,k,equals 4.7 × 10² M^-2s^-1.What is the rate of reaction when the initial concentrations of NO and O₂ are 0.025 M and 0.015 M,respectively?

Question

Quizplus · Accepted Answer

Rate = k[NO]^2[O2]
Rate = (4.7 x 10^-12)(0.025 M)^2(0.015 M)
Rate = 4.4 x 10^-13 M/s
The correct answer is B.

The Reaction of NO and O2 Produces NO2

The Reaction of NO and O₂ Produces NO₂
