Rate of reaction

Question 1

Factors effecting the rate of a reaction

Answer 1

-increasing the temperature of the reactants -increasing the concentration of a reacting solution -increasing the surface area (decreasing particle size) of a reacting solid -using a catalyst

Question 2

How to calculate the average rate of a reaction?

Answer 2

Average rate=Change in quantity/ change in time

Question 3

Whats a catalyst?

Answer 3

allows the reacting chemicals to react faster than normal but will not be used up during the reaction.

Question 4

Whats a catalysts most important use?

Answer 4

help control pollution, in particular, exhaust fumes from cars which contain poisonous chemicals, cancer causing chemicals and gases that help form acid rain.

Question 5

Describe each part of the reaction

Answer 5

A=shallow slope — are slow to get started

B =steep slope — fast reaction rate

C= shallow slope — slow down as chemicals are used up (their concentrations fall)

D =level slope — reaction has stopped,One of the chemicals

has been used up completely​
