Question
The reaction O₂(g) + 2 NO(g) → 2 NO₂(g) was studied at a certain temperature with the following results:
(a) What is the rate law for this reaction?
O Rate = k [0₂(g)] [NO(g)]
O Rate = k [0₂(g)]² [NO(g)]
O Rate = k [0₂(g)] [NO(g)]²
O Rate = k [O₂(g)]² [NO(g)]²2
O Rate = k [O₂(g)] [NO(g)]³
O Rate = k [0₂(g)]4 [NO(g)]
(b) What is the value of the rate constant?
