Rates of reaction

Front

What is the main topic of study in rates of reaction?

Back

The main topic of study in rates of reaction is how quickly reactants are converted into products in a chemical reaction.

Front

What is concentration in the context of chemical reactions?

Back

Concentration refers to the amount of a substance (solute) present in a given volume of solution.

Front

How does increasing concentration affect the rate of reaction?

Back

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

Front

What is the effect of temperature on the rate of reaction?

Back

Increasing temperature generally increases the rate of reaction because particles move faster and collide more often with greater energy.

Front

What role does surface area play in the rate of reaction?

Back

Increasing surface area allows more particles to be exposed and available for collisions, thus increasing the rate of reaction.

Front

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 collision theory?

Back

Collision theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.

Front

How does decreasing surface area affect the rate of reaction?

Back

Decreasing surface area decreases the rate of reaction because there are fewer sites available for collisions.

Front

What happens to the rate of reaction when the concentration of reactants is decreased?

Back

The rate of reaction decreases because there are fewer reactant particles available to collide.

Front

What is the relationship between reaction rate and temperature?

Back

The reaction rate typically increases with temperature due to increased kinetic energy of the particles.
