Back

+150 kJ

Front

What does the rate of a chemical reaction mean?

Back

Speed of reaction

Front

Define 'Collision Theory' in the context of reaction rates.

Back

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

Front

What factors affect the rate of a chemical reaction?

Back

Concentration, temperature, surface area, and presence of catalysts.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the reactant particles.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What role do catalysts play in chemical reactions?

Back

Catalysts increase the rate of a reaction by lowering the activation energy.
