Rate of reaction

Front

What is the rate of reaction?

Back

The rate of reaction is the speed at which reactants are converted into products in a chemical reaction.

Front

How does increasing surface area affect the rate of reaction?

Back

Increasing surface area allows more particles to collide, which increases the rate of reaction.

Front

What role does temperature play in the rate of reaction?

Back

Increasing temperature causes particles to move faster, leading to more frequent and energetic collisions, thus increasing the rate of reaction.

Front

What is a catalyst?

Back

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

Front

How does concentration affect the rate of reaction?

Back

Increasing the concentration of reactants leads to more particles in a given volume, resulting in more collisions and a faster rate of reaction.

Front

What happens to particles when the temperature is increased?

Back

Particles move faster when the temperature is increased.

Front

What is the effect of particle size on the rate of reaction?

Back

Smaller particle sizes increase the surface area, leading to a higher rate of reaction.

Front

What is the collision theory?

Back

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

Front

What is an example of a catalyst in everyday life?

Back

An example of a catalyst is the enzyme catalase, which speeds up the breakdown of hydrogen peroxide in living organisms.

Front

What is the relationship between reaction rate and time?

Back

As the reaction progresses, the rate of reaction typically decreases over time as reactants are consumed.
