Year 10 Chemistry - Rate of reaction

Rate of reaction speeds up or slows down when the surface areas of the reactants increase

• Speeds up

• Slows down

Rate of reaction speeds up or slows down when the temperature is hotter

• Speeds up

• Slows down

Rate of reaction speeds up or slows down when there is more agitation

• Speeds up

• Slows down

Rate of reaction speeds up or slows down when the concentrations of the reactants decreases

• Speeds up

• Slows down

Rate of reaction speeds up or slows down when there is a catalyst

• Speeds up

• Slows down

What are the five ways that the rate of reaction can be controlled?

• catalyst, temperature, concentration, pressure and surface area

• catalyst, temperature, fluid, volume and concentration

• pressure, surface area, fluid, volume and air

• catalyst, temperature, concentration, pressure and volume

How increasing agitation and increasing the surface area of reactants increase the rate of a reaction?

What are two examples of reactions at home that you speed up

• Cooking and freezing food

• Heating and cooking

• ice pack and freezing food

• ice pack and cooking

What are two examples of reactions at home that you slow down

• Cooking and freezing food

• Heating and cooking

• ice pack and freezing food

• ice pack and cooking

Increasing the _____________ increases the kinetic energy of particles. This increases the frequency of particle collision, and a greater proportion of collisions will have the energy required to react.

• Concentration

• Temperature

• Pressure

• Surface area

• Catalyst
