equilibrium

Examples of equilibrium in the following topics:

• Homogeneous versus Heterogeneous Solution Equilibria

  • The equilibrium constants for homogeneous and heterogeneous solutions need to be calculated differently.
  • The equilibrium constant K for a given reaction is defined as the ratio of the products of a reaction to the reactants, measured at equilibrium.
  • The reaction quotient measured at equilibrium is the equilibrium constant K.
  • A heterogeneous equilibrium is a system in which reactants and products are found in two or more phases.
  • The equilibrium constant K is simply [Br2], with the concentration of the pure liquid Br2 excluded.

• Equilibrium Constant Expression

  • The equilibrium constant is an expression that gives the ratio of reactants and products at equilibrium.
  • This constant is known as the equilibrium constant.
  • Their activity is 1, so they do not need to be written in the equilibrium constant.
  • The progress of an equilibrium reaction can be visualized.
  • The equilibrium constant,denoted by K, is the ratio of products to reactants at equilibrium.

• First Condition

  • The first condition of equilibrium is that the net force in all directions must be zero.
  • For an object to be in equilibrium, it must be experiencing no acceleration.
  • The condition $F_\text{net} = 0$ must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.
  • Below, the motionless person is in static equilibrium.
  • This car is in dynamic equilibrium because it is moving at constant velocity.

• The Zeroth Law of Thermodynamics

  • The Zeroth Law of Thermodynamics states that systems in thermal equilibrium are at the same temperature.
  • If A and C are in thermal equilibrium, and A and B are in thermal equilibrium, then B and C are in thermal equilibrium.
  • Temperature is the quantity that is always the same for all systems in thermal equilibrium with one another.
  • The double arrow represents thermal equilibrium between systems.
  • If systems A and C are in equilibrium, and systems A and B are in equilibrium, then systems B and C are in equilibrium.

• Macroeconomic Equilibrium

  • In economics, the macroeconomic equilibrium is a state where aggregate supply equals aggregate demand.
  • In economics, equilibrium is a state where economic forces (supply and demand) are balanced.
  • Without any external influences, price and quantity will remain at the equilibrium value .
  • The result is the economic equilibrium for that good or service.
  • Similar to microeconomic equilibrium, the macroeconomic equilibrium is the point at which the aggregate supply intersects the aggregate demand.

• Reaction Quotients

  • If Q < Keq, the reaction will move to the right (in the forward direction) in order to reach equilibrium.
  • If Q > Keq, the reaction will move to the left (in the reverse direction) in order to reach equilibrium.
  • Eventually, the concentrations become constant; at this point, the reaction is at equilibrium.
  • The equilibrium constant, Keq, can be expressed as follows:
  • However, most reactions will generally reach equilibrium in a finite period of time.

• The Equilibrium Interest Rate

  • In a economy, equilibrium is reached when the supply of money is equal to the demand for money.
  • Equilibrium is reached when the supply of money is equal to the demand for money.
  • Changes in expectations will therefore affect the equilibrium interest rate.
  • In economics, equilibrium is a state where economic forces such as supply and demand are balanced and without external influences, the equilibrium will stay the same.
  • Use the concept of market equilibrium to explain changes in the interest rate and money supply

• Equilibrium

  • The concentrations of A and B will change over time, until they reach equilibrium.
  • This is the point at which the system has reached chemical equilibrium.
  • While there are various factors that can increase or decrease the amount of time it takes for a given system to reach equilibrium, the equilibrium position itself is unaffected by these factors.
  • We also explain how the concentrations remain constant at equilibrium.
  • Chemical equilibrium is akin to two cities connected a bridge.

• Equilibrium

  • Equilibrium as "a point from which there is no endogenous ‘tendency to change'
  • There are no forces (from buyers or sellers) that will alter the equilibrium price or equilibrium quantity.
  • This is a mechanical, static conception of equilibrium.
  • General equilibrium is a condition where all agents acting in all markets are in equilibrium at the same time.
  • Neoclassical microeconomics tends to focus on partial equilibrium.

• Translational Equilibrium

  • This implies two types of possible equilibrium.
  • Static or dynamic, these kinds of equilibrium can be categorized as translational equilibrium.
  • Examples of translational equilibrium are all around us.
  • These six forces are in equilibrium.
  • Assess the role each type of equilibrium plays in mechanical devices
