• one of the reactant is present in excess

• one of the reactant is non-reactive

Which factors affect the rate of a reaction?

• polarity

• temperature

• presence of a catalyst

• concentration

• physical state

What is reaction half-life?

• the time required for a product concentration to reach one half of its initial value

• the time required for a reactant concentration to reach one half of its initial value

• the minimum amount of energy molucule must have for a reaction to take place

• the amount of reactant left when half of the allotted time for a reaction to take place has passed

When the species in a reaction have a coefficient, how do you adjust the reaction rate equation?

• multiply the rate by the coefficient

• add the coefficient to the rate

• divide the rate by the coefficient

• subtract the coefficient to the rate
