Rate of reaction

Question 1

Name the 4 things that affect the rate of reaction:

Answer 1

1. Increasing the Temperature
2. Increasing the concentration
3. using a catalyst
4. Increasing the surface area of a solid

Question 2

What does increasing the temperature do?

Answer 2

Causes the particles to moving quicker which means they collide more often

Question 3

What does increasing the concentration in the solution do?

Answer 3

This means there are more particles knocking about which makes collisions more likely

Question 4

What does increasing the surface area do?

Answer 4

If you increase the surface area, there will be more smaller pieces which will mean there will be more frequent collisions

Question 5

How does increasing a catalyst increase the rate of reaction?

Answer 5

It gives the reacting particles a surface to stick to. This increases the number of successful collisions.

Question 6

Name 2 ways in which a catalyst helps reduce costs in industrial reactions:

Answer 6

1. Increase rate of reaction which saves a lot of money by saving time.
2. it works at a low temperature so it saves alot of energy

Question 7

Name 3 ways of measuring the rats of reaction:

Answer 7

1. Precipitation
2. Change in mass
3. the volume of gas given off
