Rate Of Reaction

Question 1

What are all the factors which affect the rate of reaction

Answer 1

The temperature / concentration / pressure of reacting gas / surface area of reacting solids / catalysts

Question 2

When reactions happen quickly they have a

Answer 2

A high rate of reaction

Question 3

When reactions happen slowly they have a

Answer 3

Low rate of reaction

Question 4

What are the two ways to measure the rate of reaction

Answer 4

Measure the rate at which the reactant is used up and measure the rate at which the product is formed

Question 5

What can you measure

Answer 5

The mass of a substance using a balance

The volume of a gas using a syringe

Question 6

To work out the rate of reaction what do you do

Answer 6

The trade of reaction is the amount of reactant used or mount of product produces divided by the time taken

Question 7

If a solid reactant is broken into small pieces or ground into powder what happens

Answer 7

It’s surface area increases
More particles are exposed to the other reactant
More chance of particle collisions
The rate of reaction increases

Question 8

If the temperature is increased in a experiment what happens

Answer 8

The reactant particle move quicker
More particles have activation energy
More collisions
The rate of reaction increases

Question 9

Who can the rate of reaction be measured

Answer 9

By the rate at which a reactant is used up or the rate at which a product is formed
