Multiple Choice

What two factors govern whether a collision between reacting particles will be effective?

• orientation and potential energy

• kinetic energy and temperature

• kinetic energy and orientation

• potential energy and kinetic energy

Multiple Choice

More collisions correspond to a:

• Slower reaction rate
• Constant reaction rate 
• None of the above

Multiple Choice

Under the collision theory, the particles must collide with  ____ and ____ for a reaction to occur.

• sufficient rate and sufficient energy
• sufficient surface area and correct orientation
• sufficient catalyst and sufficient energy
• sufficent energy and correct orientation

Multiple Choice

Which of the following increase the reaction rate?

• less surface area
• lower temperature
• an inhibitor
• increased concentration

Multiple Choice

To slow down a chemical reaction you will do one of the following:

• Place the reactants in hot water
• Place the products in ice bath
• Place the reactants in a ice bath
• Keep stirring the reactants with a stirring rod

Multiple Choice

Why does a higher temperature increase the rate of a reaction?

• it increases both the frequency and energy of particle collisions
• it only increases the frequency of particle collisions
• it only increases the energy of particle collisions
• it reduces the activation energy of the reaction

Multiple Choice

Which of the following is NOT a factor affecting reaction rate?

• temperature
• catalysts
• particle size
• polarity
