What is chemical equilibrium in Class 11?

• Chemical Equilibrium. In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products. For example, At equilibrium the rate of forward reaction is equal to the rate of backward reaction.

What is chemical equilibrium Ncert?

When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium.

What is equilibrium in chemistry class 10?

Chemical equilibrium is defined as the state of a chemical reaction at which the rates of forward and reverse reactions are equal and the concentration of reactants and products reach constant value.

What is equilibrium in chemistry class 12?

In Chemistry, we define chemical equilibrium as a state in which the rate of the forward reaction is equal to the rate of the backward reaction. In other words, we can say it refers to the state of a system in which the concentration of the reactant and the concentration of the products do not change with time.

What is equilibrium in physics class 11?

Laws Of Motion of Class 11. A system is said to be in equilibrium if it does not tend to undergo any further change of its own. Any further change must be produced by external means (e.g. force). A body is said to be in translational equilibrium if the sum of all the forces acting on the body is zero.

What is chemical equilibrium in thermodynamics?

Chemical equilibrium is the thermodynamic equilibrium in a system where direct and reverse chemical reactions are possible. … Therefore, the macroscopic parameters of the system do not change and the relationship between concentrations of reacting substances remains constant at a given temperature.

What is chemical equilibrium PDF?

A chemical equilibrium refers to the balance of two competitive reactions ( forward and reverse) in a reversible reaction. In this dynamic process, the forward and reverse reactions proceed at the same rate.

What is the meaning of equilibrium in physics?

equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.

What is chemical equilibrium quizlet?

Chemical Equilibrium. A state in which the rates of forward and reverse reactions are the same. An active, dynamic condition, not static. All substances are being made & unmade at the same rate, so their concentrations are constant. Not necessary for products and reactants to be equal.

What is chemical equilibrium give two examples?

Chemical equilibrium. A reaction is in chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. There are many examples of chemical equilibrium all around you. One example is a bottle of fizzy cooldrink. In the bottle there is carbon dioxide (CO2) dissolved in the liquid.

What is equilibrium in diffusion?

Definition. The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal.

What is so equal about equilibrium quizlet?

A closed system has no exchange of matter with the surroundings, so equilibrium is achieved where both reactants and products can react and recombine with each other. They are being produced and destroyed at an equal rate. Macroscopic properties are observable properties such as colour and density.

What does the term equilibrium refer to quizlet?

Equilibrium. the point at which concentrations of reactants and products in a closed system remain constant.

How do you know if a reaction is at equilibrium quizlet?

When a reaction reaches equilibrium, it appears as if nothing is happening because it is balanced. Two opposing processes that occur at the same rate. The point at which the rate of the forward reaction is equal to the rate of the reverse reaction.

What is equal in a state of equilibrium?

Chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal.

Which of the following an example of an equilibrium situation?

An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady. An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.

Can physical changes reach equilibrium?

Some physical and chemical reactions are capable of reaching equilibrium. Equilibrium occurs WHEN THE OF THE FORWARD REACTION EQUALS THE OF THE REVERSE REACTION in a closed system. When equilibrium is reached, IT DOES NOT MEAN that the reactants and products are of equal QUANTITIES.

Why is it called equilibrium?

Equilibrium contains a root from the Latin libra, meaning “weight” or “balance”. … Equilibrium has special meanings in biology, chemistry, physics, and economics, but in all of them it refers to the balance of competing influences.
