What is a catalyst?
A substance that alters the rate of a reaction without being used up.
Give an analogy for a catalyst
scissors, tunnel through a mountain
True or False: A catalyst is used up during a reaction
false
True or False: catalysts produce more product
False
Why is a catalyst important for industrial production?
Costs less money, requires less energy, which means less fuel is used
give an example of a catalyst used in industry.
Iron is used in the Haber process. Platinum is used in catalytic converters
What does collision theory state?
Reacting particles need to collide with a certain amount of energy in order to suucessfully react
How would you measure the rate of reaction?
Measure how much product is formed/ how much reactant is used up over time
What five things affect the rate of a reaction?
Temperature, concentration, pressure, surface area and the use of a catalyst
Which of these would decrease the rate of reaction: Increasing temperature, increasing concentration, decreasing surface area, or using a catalyst?
decreasing surface area
Which has a larger surface area: Marble chips in a fine powder, or large chunks of marble chips?
Marble chips in a fine powder
Which piece of equipment would you use to measure the amount of gas produced?
Syringe,.inverted measuring cylinder full of water
What does "activation energy" mean?
The minimum amount of energy that particles need to collide with in order to react.
What five pieces of equipment would you need in order to measure the rate of an exothermic reaction?
polystyrene cup, lid, thermometer, timer, measuring cylinder
