What is Reaction Dynamics?

Back

Reaction Dynamics is the study of the rates of chemical reactions and the factors that affect these rates, including concentration, temperature, and catalysts.

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a chemical system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.

What is a catalyst?

Back

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

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

How does increasing concentration affect reaction rates?

Back

Increasing the concentration of reactants generally increases the rate of reaction because it leads to more frequent collisions between reactant molecules.

Front

What happens to the equilibrium position when pressure is increased?

Back

The equilibrium position shifts towards the side with fewer moles of gas when pressure is increased.

Front

What is activation energy?

Back

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

Front

What is the role of temperature in chemical reactions?

Back

Increasing temperature generally increases the rate of a chemical reaction by providing more energy to the reactant molecules, leading to more frequent and effective collisions.

Front

What is the effect of surface area on reaction rates?

Back

Increasing the surface area of a solid reactant increases the rate of reaction because it allows more particles to collide with reactants.
