| /slower
| /
Loss in mass (grams)| / fast
|/
|_________________
Time(mins)

Question 2

What’s a catalyst

Answer 2

A catalyst is a substance which alters the rate of a reaction without getting used up.

Question 3

What happens when u add a catalyst

Answer 3

When you add a catalyst it lowers the activation energy; this makes it easier for the particles to react, so there is an increase in the rate of reaction.

Question 4

What is activation energy

Answer 4

Activation energy is the minimum amount of energy that reactant particles must have in order for them to react.

Question 5

What is activation energy

Answer 5

Activation energy is the minimum amount of energy that reactant particles must have in order for them to react.
