4.6 Reversible Reactions

Question 1

In some chemical reactions, the products of the reaction can
react to produce the original reactants. Such reactions are
called reversible reactions and are represented:

Answer 1

A+B ⇌ C+D

Question 2

the ⇌ sign shows

Answer 2

a reversible reaction is occuring

Question 3

the forward reaction is the one that goes to

Answer 3

the right

Question 4

the backwards reaction is the one that goes to

Answer 4

the left

Question 5

If a reaction is exothermic in one direction, it will be…

Answer 5

exothermic in the other direction

Question 6

endothermic means

Answer 6

the absorbing of heat

Question 7

exothermic means

Answer 7

the release of heat

Question 8

Equilibrium is reached, when the

Answer 8

forward and reverse reactions occur at exactly the

same rate.

Question 9

When a reversible reaction happens in a closed container, it reaches a dynamic equilibrium. At equilibrium:

Answer 9

the forward and backward reactions are still happening

the forward and backward reactions have the same rate of reaction

the concentrations of all the reacting substances remain constant
