Rate Of Reaction

Question 1

What is a catalyst?

Answer 1

A catalyst is something that speeds up a reaction without being used up itself

Question 2

How do you calculate Rate of Reaction?

Answer 2

Quantity of reactants used/Time taken or quantity of product formed/time taken

Question 3

How does a catalyst work?

Answer 3

It speeds up a reaction by providing a lower energy pathway

Question 4

What is rate of reaction?

Answer 4

Rate of Reaction (RoR) is the speed at which reactants become products

Question 5

What affects rate of reaction?

Answer 5

Catalysts, temperature, concentration/pressure, surface area

Question 6

What are the three main methods for measuring ROR?

Answer 6

Measuring the volume of gas produced over time, measuring the loss in mass over time(when a gas is being produced), measuring the formation of a precipitate over time

Question 7

What is needed for a reaction to be successful?

Answer 7

Particles need to collide with activation energy and with the correct orientation

Question 8

What is concentration?

Answer 8

Concentration is a measure of the amount or number of reactant particles in a given volume

Question 9

Define Rate of Reaction?

Answer 9

Number of fruitful reaction/s between reactants

Question 10

How can pressure increase ROR in gases?

Answer 10

Pressure increase leads to volume decrease and decrease in volume leads to increase in concentration
