Question

Define dynamic equilibrium.




( still remember me rehbar bhaiya? )​

Answer 1

Dynamic Equilibrium:

• In chemistry and physics, a dynamic equilibrium exists once a reversible reaction occurs. Substances transition between the reactants and the products at equal rates, meaning there is no net charge.
• Reactants and products are formed at such a rate that the concentration of neither changes. It is a particular example of the system in a steady state.
• In thermodynamics, a closed system is in thermodynamic equilibrium when reactions occur at such rates that the composition of the mixtures does not change with time.
• Reactions do in fact occur, sometimes vigorously, but to such an extent that changes in composition cannot be observed.
• Equilibrium constants can be expressed in terms of the rate constants for reversible reaction.
• Example:

                       NO2(g)+ CO(g)⇄NO(g)+ CO2(g)

              (again ,as long as the two rates are equal.)
