the rate of chemical change

What is the rate of chemical change?

The rate of chemical change refers to how fast a reaction occurs, typically measured by the change in concentration of reactants or products over time.

What factors affect the rate of chemical change?

Factors include concentration of reactants, temperature, surface area, the presence of catalysts, and the nature of the reactants.

What is a catalyst?

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

How does temperature influence chemical change?

Increasing the temperature generally increases the rate of a chemical reaction because it raises the energy of the molecules involved.

What is the extent of chemical change?

The extent of chemical change refers to how far a reaction proceeds toward completion, often measured by the equilibrium position.

What is dynamic equilibrium in chemical reactions?

Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction, and concentrations of reactants and products remain constant.

How does concentration affect the rate of reaction?

Higher concentrations of reactants usually lead to an increased rate of reaction due to a greater number of particles colliding.

What role does surface area play in chemical reactions?

Increasing surface area of solid reactants can enhance the rate of reaction by allowing more collisions between reactants.

What are endothermic and exothermic reactions?

Endothermic reactions absorb heat, while exothermic reactions release heat during the chemical change.

What is activation energy?

Activation energy is the minimum amount of energy required for a chemical reaction to occur.
