What are the two kinds of equilibrium?
The two kinds of equilibrium are static equilibrium, where an object is at rest with no linear or angular acceleration, and dynamic equilibrium, where an object is moving at a constant velocity with no linear or angular acceleration.
Are there any balanced forces acting on the freezer?
If the freezer is stationary or moving at a constant velocity, then yes, there are balanced forces acting on it. The forces pushing the freezer forward or backward are equal in magnitude and opposite in direction, resulting in a state of equilibrium.
When does an equilibrium occur?
An equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. Equilibrium can only be reached in a closed system under certain conditions, such as constant temperature and pressure.
What is meant by law of equilibrium?
The law of equilibrium refers to the condition where two opposing forces or factors are balanced and cancel each other out. In the context of physics, it describes the state when an object is either stationary or moving at a constant velocity with zero net force acting on it. This law is fundamental in understanding the stability and behavior of systems in various fields of science and engineering.
What does positive velocity means?
Positive velocity refers to an object moving in the positive direction along its path. It indicates that the object is moving forward or in the direction of increasing position. Velocity is a vector quantity that includes both magnitude (speed) and direction.
In a reaction the equilibrium constant for the forward reaction is Kf and the equilibrium constant of the backward reaction is KB What is the relationship between Kf and KB?
The relationship between Kf and KB is that they are reciprocals of each other. Mathematically, Kf = 1/KB. This means that if Kf is large, then KB will be small and vice versa.
When do the macroscopic properties become constant in an equilibrium system?
when forward and reverse reaction rates are equal
What is the correct statement of the equilibrium?
The correct statement of equilibrium is that the rates of the forward and reverse reactions are equal, leading to a constant concentration of reactants and products over time.
When a reaction system is at equilibrium the rates of the reaction in the forward and reverse directions are?
Equal. At equilibrium, the rates of the forward and reverse reactions are balanced, meaning that the rate of the forward reaction is equal to the rate of the reverse reaction. This results in no net change in the concentrations of reactants and products over time.

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.
If a car is traveling on the highway at a constant velocity the force that pushes the car forward must be?
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back
What law of motion is it when stopping a car you are thrown forward?
Newton's first law of motion states that any object at equilibrium, i.e. stationary or at constant velocity, will continue in that state unless acted on by a force. In reality, you are not thrown forward in the car. Its a matter of perspective. The car decelerates, i.e. force in negative direction to velocity due to friction from the brakes, and you continue moving forward until you reach whatever restraint is going to force you also to decelerate.
What equilibrium concentrations are affected by changing the initial concentration?
Yes, the concentrations are constant but not necessarily static. The 'forward' reaction rate matches the 'reverse' reaction rate.
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 causes a force to produce motion?
A force causes motion by overcoming any opposing forces (such as friction or inertia) acting on an object. When the force applied is greater than the resisting forces, the object will start to move in the direction of the force.
Why person jumping out of a speeding train fall forward?
When a person jumps out of a speeding train, they still retain the forward velocity of the train due to inertia. As they hit the ground, the friction between their feet and the ground causes a torque, which rotates their body forward in the direction of motion before coming to a stop.
