Factors Affecting Rate of Reaction

Front

What factors affect the rate of reaction?

Back

Factors include concentration, surface area, temperature, pressure, catalysts, and inhibitors.

Front

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

Back

Increasing concentration generally increases the rate of reaction due to more frequent collisions between reactant particles.

Front

How does surface area affect the rate of reaction?

Back

Increasing surface area increases the frequency of collisions, thus increasing the rate of reaction.

Front

What role do catalysts play in chemical reactions?

Back

Catalysts increase the rate of reaction without being consumed in the process.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for particles to collide and react.

Front

What happens to the rate of reaction when temperature increases?

Back

Increasing temperature typically increases the rate of reaction due to higher kinetic energy of particles.

Front

What is the collision theory?

Back

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

Front

What is the effect of pressure on the rate of reaction for gases?

Back

Increasing pressure increases the rate of reaction by reducing the volume and increasing the frequency of collisions.

Front

What observation indicates a chemical reaction has occurred?

Back

Indicators include color change, gas production, temperature change, or formation of a precipitate.

Front

What is the relationship between the mass of a catalyst and the rate of reaction?

Back

The greater the mass of catalyst, the increases the rate of reaction.
