- 1. Multiple ChoiceReaction rate means...amount of product formedspeed of reactionconcentration of reacting particlescombining reactants with products
- 2. Multiple ChoiceTo slow down a chemical reaction you will do one of the following:Place the reactants in hot waterPlace the products in ice bathPlace the reactants in a ice bathKeep stirring the reactants with a stirring rod
- 3. Multiple Choice
Which of the following increase the reaction rate?
less surface area
lower temperature
increasing pressure
increased concentration
- 4. Multiple ChoiceA catalyst works bychanging the order of the reactionincreasing the temperaturelowering the activation energymaking the activated complex
- 5. Multiple ChoiceThe rate of a chemical reaction is NOT affected by which of the following:temperatureconcentrationparticle size (surface area)All of these affect reaction rates
- 6. 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]
- 7. Multiple Choice
If the concentration of [A] is doubled, and the rate of the reaction also doubles. What reaction order is [A]?
Zero-order
First-order
Second-order
Triple-order
- 8. Multiple Choice
If we double the concentration of a reactant and the rate quadruples, what rate order is this?
first order
second order
third order
eighth order
- 9. Multiple Choice
What is the overall rate order of this chemical rate law:
Rate = k
zero-order
first-order
second-order
third-order
- 10. Multiple Choice
Look at the rate equation: Rate=k[H2O][HCl]
What is the overall order of the reaction?
first-order
second-order
third-order
fourth-order
- 11. Multiple Choice
Which trials would be used to measure the rate exponent for A?trials 1 and 2trials 1 and 3trials 2 and 3 - 12. Multiple Choice
For a reaction 2A + B --> 2C, with the rate equation:
Rate = k [A]2 [B]
The order with respect to A is 1 and the order overall is 1
The order with respect to A is 2 and the order overall is 2
The order with respect to A is 2 and the order overall is 3
The order with respect to B is 2 and the order overall is 3
The order with respect to B is 2 and the order overall is 2
- 13. Multiple ChoiceThe only factor that can change the value of k is:concentrationa catalystsurface areatemperature
