Increase in temperature of the reactants can do one of the following

• Slow collision frequency
• Allow less effective collision between the particles
• Cause particles to lose speed
• Increase collision between the particles thus increasing the rate.

Grinding a seltzer tablet into powder increases the rate of reaction due to increased

• concentration
• surface area
• temperature
• reactants

Increasing the concentration of the reactants will slow down the reaction.

• false 
• true

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

• 1st
• 2nd
• 3rd
• 4th

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

• 1st
• 2nd
• 3rd
• 4th

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]

A 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 3
• increases by a factor of 4
• increases by a factor of 5
• increases by a factor of 6

Which two trials would you use to find the rate exponent for A?

• trials 1 and 2
• trials 1 and 3
• trials 2 and 3

What is the rate exponent for A?

• 0
• 1
• 2

The rate law of any chemical reaction 

• must be determined experimentally
• can be deduced based on the stoichiometry of the reaction
• changes based on the condition of the experiment
