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

What factors affect the rate of reaction?

Back

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

Front

How does temperature affect the rate of reaction?

Back

Increasing temperature generally increases the rate of reaction by increasing the energy and frequency of particle collisions.

Front

What is activation energy?

Back

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

Front

Why do not all collisions between particles result in a reaction?

Back

Not all collisions result in a reaction because particles must collide with sufficient energy and proper orientation.

Front

What effect does increasing concentration have on the rate of reaction?

Back

Increasing concentration increases the frequency of collisions between reactant particles, leading to a higher 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 surface area affect the rate of reaction?

Back

Increasing the surface area of reactants allows more collisions to occur, thus increasing the rate of reaction.

Front

What is the relationship between particle size and reaction rate?

Back

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

Front

What happens to the rate of reaction when reactants are placed in an ice bath?

Back

The rate of reaction decreases because the lower temperature reduces the energy and frequency of particle collisions.
