AP CHEM Unit 5 Days 1-3 REVIEW

Front

What does collision theory state?

Back

Molecules must collide with the proper orientation in order to react.

Front

Which factor does NOT increase the speed of a combustion reaction?

Back

High activation energy.

Front

What is the rate of decomposition of N2O5 if the rate of formation of NO2 is 5.78 (mol NO2)/L/s?

Back

2.89 (mol N2O5)/L/s.

Front

What is the order of reaction if the graphical data shows a straight line with a slope?

Back

Zero order.

Front

How do you calculate the concentration of BrO3- remaining after 75% of H+ has been consumed?

Back

0.075M [BrO3-] remaining.

Front

Define activation energy.

Back

The minimum energy required for a chemical reaction to occur.

Front

What is a catalyst?

Back

A substance that increases the rate of a reaction without being consumed.

Front

Explain the concept of reaction rate.

Back

The change in concentration of reactants or products per unit time.

Front

What is the difference between a zero-order and a first-order reaction?

Back

Zero-order: rate is constant; First-order: rate depends on the concentration of one reactant.

Front

What is a transition state in a chemical reaction?

Back

A high-energy state during the conversion of reactants to products.
