Describe the macroscopic characteristics of an equilibrium reaction.

Macroscopic characteristics of an equilibrium reaction: The macroscopic characteristics of an equilibrium reaction are: 1. Constant concentrations of reactants and products: The concentrations of all substances remain unchanged over time. 2. No observable changes: There are no visible changes in color, pressure, or other measurable properties. 3. Temperature-dependent: The equilibrium position depends on temperature; increasing … Read more

State the ways that equilibrium can be recognized.

Ways to recognize equilibrium: Equilibrium can be recognized by the following characteristics: 1. Constant macroscopic properties: Observable properties like color, pressure, and concentration remain constant at equilibrium. 2. Equal forward and reverse reaction rates: The rate of the forward reaction equals the rate of the reverse reaction. 3. Dynamic nature: Molecules continue to react, but … Read more

State law of mass action?

The Law of Mass Action states: The rate of a chemical reaction is directly proportional to the product of the molar concentrations of the reactants, each raised to the power of its respective stoichiometric coefficient in the balanced chemical equation. Mathematical Representation: For a general reaction: aA+bB→PRODUCT The rate of the reaction is: Rate∝[A]a[B]b Where: … Read more

How does temperature affect the equilibrium constant?

For exothermic reactions, an increase in temperature decreases the value of Kc. For endothermic reactions, an increase in temperature increases the value of Kc.

What is dynamic equilibrium?

Dynamic equilibrium: Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction in a reversible reaction, with no net change in the concentrations of reactants and products.

Why does a catalyst not affect the position of equilibrium?

A catalyst speeds up both the forward and reverse reactions equally, so it does not change the relative concentrations of reactants and products at equilibrium. It only helps the system reach equilibrium faster. Related Questions: Differentiate between reversible and irreversible reactions? State Le-Chatelier’s principle.

What is the significance of the equilibrium constant (Kc)?

The equilibrium constant (Kc) expresses the ratio of the concentrations of products to reactants at equilibrium. It indicates whether products or reactants are favored in the reaction.

State Le-Chatelier’s principle.

Le-Chatelier’s principle : If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the equilibrium will shift to counteract the imposed change and establish a new equilibrium, this phenomenon is known as Le-Chatelier’s principle.
