- 1. Multiple ChoiceA reaction has the rate law: Rate = k [A][B].
What is the order of reaction with respect to A?1st2nd3rd4th - 2. Multiple ChoiceA reaction has the rate law: Rate = k [A][B].
What is the overall order of reaction?1st2nd3rd4th - 3. Multiple ChoiceA possible rate law for a third overall order of a reaction is __________________Rate = k [A]2[B]2Rate = k [A][B]3Rate = k [A]3 [B]Rate = k [A]2[B]
- 4. Multiple ChoiceWrite the rate law for the reaction aA → bB if the reaction is third order in A. [B] is not part of the rate law.Rate =k[A]Rate =3[A]Rate =k[3A]Rate =k[A]3
- 5. Multiple ChoiceA reaction has the rate law: Rate = k [A][B].
What will happen to the rate of reaction if the concentration of A is doubled and the concentration of B is tripled?increases by a factor of 3increases by a factor of 4increases by a factor of 5increases by a factor of 6 - 6. Multiple ChoiceThe rate law for the reaction 2NO(g) + O2(g) → 2NO2(g) is first order in O2 and third order overall. What is the rate law for the reaction?Rate = k [NO]2[O2]2Rate = k [NO]1[O2]2Rate = k [NO]2[O2]1Rate = k [2NO]2[O2]1
