Question 5

__________ - This means that the reactants can act together to form product(s) and product(s) can also be converted to reactants.

Answer 5

Reversible

Question 6

_________ - reverse reaction, reactants does NOT occur.

Answer 6

irreversible reaction

Question 7

__________ - is the rate of change of reactants to product(s) or vice versa.

Answer 7

Reaction rate

Question 8

What are the four factors that affects the reaction rate?

Answer 8

1. Concentration of reactant(s)
2. Temperature
3. Activation Energy (AE)
4. Catalyst

Question 9

___________ - it is the amount of energy needed to break particular bonds and results in molecules reacting together.

Answer 9

Activation Energy (AE)

Question 10

____________ - Occurs when rates of forward and reverse reactions are equal.

Answer 10

Chemical equilibrium

Question 11

This law is used to manipulate chemical reactions by changing concentrations of reactants or products depending on which direction we want the reaction to proceed (forward or reverse).

Answer 11

Law of mass action

Question 12

State if True or False:

Law of mass action:

” States that if increase reactant concentration, thus reaction will proceed (forward) in the direction of product formation and vice versa “

Answer 12

True
