How Concentration Of Reactants Affects Rate Of Reaction

Question 1

What affect does an increase in the concentration of the reactants have on the rate of reaction?

Answer 1

An increase in concentration of the reactants usually increases the rate of the reaction

Question 2

Give an example of a reaction where the concentration of reactants has an affect on the rate of reaction.

Answer 2

The decomposition of hydrogen peroxide using manganese (IV) oxide as a catalyst

Question 3

What happens when a more concentrated peroxide solution is used in the decomposition of hydrogen peroxide using manganese (IV) oxide as a catalyst

Answer 3

The oxygen gas is produced more rapidly

Question 4

What catalyst is used in the decomposition of hydrogen peroxide into water and oxygen gas?

Answer 4

Manganese (IV) oxide

Question 5

What are the products of the reaction between hydrogen peroxide in aqueous solution and manganese (IV) oxide?

Answer 5

Water and Oxygen gas
