Energy is always conserved in a chemical reaction. If heat of reaction is positive, the mixture gets heated and may require external cooling to continue the reaction in the forward direction. If the reaction is endothermic, i.e. heat of reaction is negative, the mixture gets cooled and may need external supply of heat to maintain the reaction in forward direction. When the reaction is at an equilibrium, the heat of reaction is either zero or the mixture has attained an equilibrium with some definite ratios of the reaction products. The total energy of the system is conserved.

What is dynamic metastable equilibrium?
Dynamic Metastable Equilibrium as it relates to Geomorphology describes a system threshold that changes dramatically through time, in an otherwise steady system. In other words, it is a combination of dynamic equilibrium and metastable equlibrium. An example would be changing sea level as it respositions shorelines these changes typically ocurr over thousands of years.
Are most chemical reactions at equilibrium in living cells?
No, most chemical reactions in living cells are not at equilibrium. Cells maintain a dynamic balance, constantly adjusting reaction rates to respond to changing conditions and maintain homeostasis. Equilibrium is rare in living systems due to the constant flux of molecules and energy.
What happens to thermal energy in a beaker when it is cooled down?
When a beaker is cooled down, thermal energy is transferred from the beaker to the surroundings. The molecules in the beaker lose kinetic energy, which causes the temperature of the beaker to decrease. This transfer of thermal energy continues until the beaker reaches thermal equilibrium with its surroundings.
Is G at equilibrium equal to zero?
Yes, at equilibrium, the standard Gibbs free energy change (G) is equal to zero.
How can one determine the equilibrium constant from the change in Gibbs free energy (G)?
To determine the equilibrium constant from the change in Gibbs free energy (G), you can use the equation G -RT ln(K), where G is the change in Gibbs free energy, R is the gas constant, T is the temperature in Kelvin, ln is the natural logarithm, and K is the equilibrium constant. By rearranging this equation, you can solve for K to find the equilibrium constant.
When do you know dynamic equilibrium as occurred in a solution?
When it no longer absorbs or emits energy from the surroundings.
What happens to energy in open system?
Energy can enter or exist an open system
How are photosynthesis and cellular respiration reactions in dynamic equilibrium?
Photosynthesis and cellular respiration are interconnected as the products of one process are utilized as reactants in the other. They are not in a static equilibrium but rather a dynamic equilibrium where they continuously occur simultaneously to maintain a balance in the availability of energy and nutrients in the ecosystem. This balance ensures the cycling of carbon and energy between producers and consumers in the environment.
Explain the difference between static equilibrium and dynamic equilibrium?
A chair has static equilibrium ... a bicycle has dynamic equilibrium.Dynamic implies movement while staticimplies stationary, but that is a bit misleading. Take an object traveling with a constant velocity in deep space (no air resistance and no gravity). It could be viewed as being as much at rest as an object sitting on a table. The mathematical or chemical use of equilibrium is better. In these cases there is no net change over time even though energy maybe expended. If a steady-state situation in which a reverse process is occurring has a corresponding forward process, at a rate which achieves an exact balance, it is said to be in dynamic equilibrium. With regard to the pressure and volume of water sealed in an exhausted vessel at a constant temperature, a balanced state of constant change is possible in which molecules are constantly being exchanged between ice, water, and water vapour phases. By definition this balanced state of constant change is dynamic equilibrium. Static equilibrium can refer to a steady-state situation with no dynamic forces acting on its potential energy in either reverse or forward processes. By definition, in a state of staticequilibrium there is balance, but no change, disturbance or movement.
What is dynamic equilibrium Describe what is happening to the liquid and vapor at the boundary of a liquid that is in dynamic equilibrium Is the overall balance of liquid and vapor changing?
1. Dynamic equilibrium is when the rate of vapour and liquid being produced has stabilized, and stopped changing. It's called dynamic equilibrium because the liquid hasn't stopped changing into vapour, and the vapour hasn't stopped changing into liquid, but the rates of these two changes has stabilized so that there is a constant amount of liquid and vapour present.2. At the boundary of the liquid, particles with sufficient energy break away from the liquid and become vapours, and vapour molecules with low energy, or those that make contact with the surface of the liquid, become bonded to the liquid. There is a constant exchange of particles, hence dynamicequilibrium3. No, the overall balance of liquid is constant, hence equilibrium.
What is true about the rate of evaporation in a dynamic equilibrium between the liquid state and the gas state?
It Occurs as water moleclues absorb energy and it also occurs at the surface of liqud.

Where does dynamic equilibrium take place?
Dynamic equilibrium takes place in a closed system where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, even though the reactions continue to occur. Examples include chemical reactions, such as the Haber process for ammonia production.
What shape would the graph of U versus x have if a particle were in a region of neutral equilibrium?
In neutral equilibrium, displacement in either direction would not affect the potential energy of the particle, therefore, the graph would be horizontal.
When you stretch out a spring at what point would you have the greatest potential energy?
A spring has maximum potential energy at maximum displacement from equilibrium. This means that the greatest potential energy will occur when a spring is stretched as far as it will stretch or compressed as tightly as it will compress. In an oscillating system, where an object attached to a spring is moving back and forth at a given frequency, the object will oscillate about the equilibrium point, and the potential energy of the system will be greatest (and equal) when the object is farthest from equilibrium on either side.
What is difference between static energy and dynamic energy?
Static energy refers to the potential energy stored in an object at rest, such as an object sitting on a shelf. Dynamic energy, on the other hand, refers to the energy of an object in motion, like a moving car or a flowing river. In summary, static energy is associated with stationary objects, while dynamic energy involves objects in motion.
