Kinetics and Equilibrium

Front

What is Kinetics?

Back

Kinetics is the study of the rates of chemical reactions and the factors that affect these rates.

Front

What is Equilibrium in a chemical reaction?

Back

Equilibrium is the 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

How does temperature affect reaction rates?

Back

Higher temperatures increase the rate of a reaction by increasing both the frequency and energy of particle collisions.

Front

What is Activation Energy?

Back

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

Front

What is an Endothermic reaction?

Back

An endothermic reaction is a reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What is an Exothermic reaction?

Back

An exothermic reaction is a reaction that releases energy to its surroundings, usually in the form of heat.

Front

What is an Effective Collision?

Back

An effective collision occurs when molecules collide with the proper orientation and sufficient kinetic energy to result in a reaction.

Front

What does ΔH represent in a reaction?

Back

ΔH represents the change in enthalpy, or heat content, of a system during a reaction.

Front

What is the difference between a catalyst and an inhibitor?

Back

A catalyst increases the rate of a reaction by lowering the activation energy, while an inhibitor decreases the rate of a reaction.

Front

What is the role of concentration in reaction rates?

Back

Increasing the concentration of reactants generally increases the rate of reaction due to a higher frequency of collisions.
