Rate Law Intro

A possible rate law for a third overall order of a reaction is __________________

• Rate = k [A]²[B]²
• Rate = k [A][B]³
• Rate = k [A]³ [B]
• Rate = k [A]²[B]

Which of the following is a characteristic of a first-order reaction?

• The rate is proportional to the square of the concentration of one reactant.

• The rate is directly proportional to the concentration of one reactant.

• The rate is independent of the concentration of reactants.

For a reaction with the rate law Rate = k [A][B], what is the overall order of the reaction?

• Third order

• Second order

• First order

A reaction has the rate law: Rate = k [A][B].
What is the overall order of reaction?

• 1st
• 2nd
• 3rd
• 4th

A reaction has the rate law: Rate = k [A][B].
What is the order of reaction with respect to A?

• 1st
• 2nd
• 3rd
• 4th

The rate law for the reaction 2NO_(g) + O_2(g) → 2NO_2(g) is first order in O₂ and third order overall. What is the rate law for the reaction?

• Rate = k [NO]²[O₂]²
• Rate = k [NO]¹[O₂]²
• Rate = k [NO]²[O₂]¹
• Rate = k [2NO]²[O₂]¹
