Rates Of Reaction And Reversible Reactions

Question 1

Factors affecting the rate of reaction

Answer 1

Temperature
Concentration
Surface area
Catalyst

Question 2

Temperature with rates of reaction

Answer 2

When the temperature is increased the particles all move faster.
The faster they move, the more collisions per second and the faster they move the more energy they have so they are more likely to reach the activation energy

Question 3

Concentration and the rate of reaction

Answer 3

If there are more particles in the same volume of water then there will be more collisions per second and more likely to have the reaction

Question 4

Surface area and the rate of reaction

Answer 4

The larger the surface area the more collisions per second and therefore a faster rate of reaction

Question 5

Catalyst to increase the rate

Answer 5

The catalyst provides a different route that lowers the activation energy

Question 6

Colour change and measuring rates of reaction

Answer 6

By placing a piece of paper with a cross underneath and a reaction like sodium thiosulfate and HCl which makes the liquid go cloudy and time how long it takes for the cross to be out of view

Question 7

Reversible reactions

Answer 7

These are just reactions that go back and forth. An example of this is hydrated copper sulfate👉👈anhydrous copper sulfate and water
