Describes chemical equilibrium?
Chemical equilibrium is a term used to describe a balanced condition within a system of chemical reactions. Essentially, when in chemical equilibrium, substances becomes definite and constant.
What is the relationship between chemical potential and Gibbs free energy in a chemical system?
In a chemical system, the chemical potential is related to the Gibbs free energy. The chemical potential represents the energy required to add one molecule of a substance to the system, while the Gibbs free energy is a measure of the system's overall energy available to do work. The relationship between the two is that the change in Gibbs free energy of a reaction is related to the change in chemical potential of the reactants and products involved in the reaction.
What is the relationship between temperature and molar entropy in a chemical system?
The relationship between temperature and molar entropy in a chemical system is that as temperature increases, the molar entropy also increases. This is because higher temperatures lead to greater molecular motion and disorder, resulting in higher entropy.
What characterizes a system of equilibrium?
A system of equilibrium is characterized by a balance between opposing forces or processes, where no net change occurs over time. The system remains stable and does not shift in response to small disturbances. In an equilibrium state, the rates of forward and reverse reactions are equal, leading to a dynamic but constant system.
When does chemical equilibrium occur?
When reactants and the products that are also contributing to a chemical reaction show no sign over change over time, chemical equilibrium has taken place. Chemical equilibrium can be called a "steady state reaction". It must be noted, however, that just because nothing has changed, it doesn't necessarily indicate that the interaction has stopped.
Why phase diagram is called equilibrium diagram?
A phase diagram of the equilibrium relationship between temperature, pressure, and composition in any system.
What requirements should a system need in order to be in thermodynamic equilibrium?
A system should be in thermal equilibrium when it has a homogeneous temperature throughout, mechanical equilibrium when there is no net force acting on it, and chemical equilibrium when there are no gradients in chemical potential.
What does Le chateliers principles say about upsetting a system at equilibrium?
Le Chatelier's principle says that if a system in chemical equilibrium is disturbed, the system will move in such a way as to nullify that change.

Does a battery represent a system at equilibrium?
No, a battery does not represent a system at equilibrium. A battery operates by creating a potential difference between its terminals through chemical reactions, which is a non-equilibrium process as it involves the flow of electrons from one terminal to the other.
What is equilibrium parameters?
Equilibrium parameters refer to the specific conditions, such as temperature, pressure, and chemical composition, at which a system is in thermodynamic equilibrium. These parameters define the state of the system where the rates of forward and reverse reactions are equal, resulting in no net change in the system's properties over time. Equilibrium parameters are crucial in understanding and predicting the behavior of chemical and physical systems.

The chemical potential represents the energy required to add one molecule of a substance to the system, while the Gibbs free energy is a measure of the system's overall energy available to do work. The relationship between the two is that the change in Gibbs free energy of a reaction is related to the change in chemical potential of the reactants and products involved in the reaction.
What relationship is discussed in the Zeroth law of thermodynamics?
The Zeroth Law of Thermodynamics establishes the concept of thermal equilibrium and defines temperature. It states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This relationship allows for the comparison of temperatures between different systems and forms the basis for the measurement of temperature.
What is the relationship between temperature and molar entropy in a chemical system?
The relationship between temperature and molar entropy in a chemical system is that as temperature increases, the molar entropy also increases. This is because higher temperatures lead to greater molecular motion and disorder, resulting in higher entropy.

What does Le chateliers principal say about upsetting system at equilibrium?
Le Chatelier's Principle states that when a chemical system at equilibrium is disturbed by a change in conditions, the system will shift to counteract the change and establish a new equilibrium. This can involve changes in concentration, pressure, or temperature to minimize the disturbance.
How does Le Chatelier's Principle apply to chemical systems?
Le Chatelier's principle is very important in studying the chemical systems in equilibrium. It states if an external stress is applied to a system in equilibrium, then the equilibrium shifts in a direction where the change can be neutralized.
