Chem: Kinetics, Equilibrium

Front

What is chemical kinetics?

Back

The study of the rates of chemical reactions and the factors affecting them.

Front

Define equilibrium in a chemical reaction.

Back

A state in which the concentrations of reactants and products remain constant over time, indicating that the forward and reverse reactions occur at the same rate.

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

What factors affect the rate of a chemical reaction?

Back

Temperature, concentration of reactants, surface area, presence of a catalyst, and pressure (for gases).

Front

What is the role of a catalyst in a chemical reaction?

Back

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

Front

Explain the concept of entropy in thermodynamics.

Back

A measure of the disorder or randomness in a system; systems tend to move towards higher entropy.

Front

What does it mean if a reaction has a negative ∆H?

Back

The reaction is exothermic, meaning it releases heat.

Front

What is the relationship between temperature and reaction rate?

Back

Generally, increasing the temperature increases the reaction rate by providing more energy to the reactants.

Front

What is dynamic equilibrium?

Back

A condition where the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in concentration.
