2nd Science Titrations, Rates of reaction & Exo/Endothermic

List four factors that affects the rate of a reaction

• temperature

• concentration

• surface area

• volume

• catalysts

A temperature increase causes the particles ......

• to slow down

• move faster

• collide higher

• in the right order

How does a catalyst work in speeding up a reaction?

• By lowering the activation energy or reaction

• by giving them more energy

• by making them more available

In an exothermic reaction, heat is ...

• taken in
• given out

Why does a higher concentration increase the rate of reaction?

• it increases the amount of reactants

• it lowers the activation energy

• it increases the energy of particle collisions

• it increases the frequency of particle collisions

The ______________is required to break the bonds of the reactants.

• Carbonic energy

• Activation energy

• Plutonic energy

• Energi Gaib

Why don't all collisions between particles cause a reaction?

• the particles also need to collide with a catalyst
• not all the particles collide with enough energy
• not all the particles collide at a high enough temperature
• the particles need to collide with each other twice

What is the rate of reaction?

• How fast a reaction is 
• How big a reaction is
• How loud a reaction is
• How much gas a reaction produces

Located on the left side of the reaction

• reactants
• products

The minimum amount of energy needed for colliding particles to react is called

• Chemical Energy

• Kinetic Energy

• Activation Energy

• Potential Energy
