AP Chem Kinetics Review

Front

What factors can increase the rate of a chemical reaction?

Back

Factors that can increase the rate of a chemical reaction include increasing temperature, increasing concentration of reactants, adding a catalyst, and increasing the surface area of reactants.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does a catalyst affect activation energy?

Back

A catalyst speeds up a reaction by lowering the activation energy required for the reaction to proceed.

Front

What is the effect of lowering the concentration of reactants on the rate of reaction?

Back

Lowering the concentration of reactants decreases the rate of reaction because it reduces the number of collisions between reactant particles.

Front

What is the relationship between temperature and reaction rate?

Back

Increasing the temperature generally increases the reaction rate because it provides reactant particles with more energy, leading to more frequent and effective collisions.

Front

What does the term 'reaction mechanism' refer to?

Back

A reaction mechanism is the step-by-step sequence of elementary reactions by which overall chemical change occurs.

Front

What role do intermediates play in a reaction mechanism?

Back

Intermediates are species that are formed during the reaction mechanism but are not present in the final products.

Front

What is the collision theory?

Back

Collision theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.

Front

How does increasing surface area affect reaction rate?

Back

Increasing the surface area of reactants allows for more collisions between reactant particles, thus increasing the reaction rate.

Front

What is the effect of a catalyst on the equilibrium of a reaction?

Back

A catalyst does not affect the position of equilibrium; it only speeds up the rate at which equilibrium is reached.
