Question 10

Le charlie’s principles

Answer 10

when a system in equilibrium is distributed the system will adjust to counteract this disturbance

Question 11

if a certain reversible reaction was at equilibrium what would happen to this equilibrium if more recants were added.

Answer 11

The equilibrium would shift to form more products

Question 12

what is meant by the phrase “ the equilibrium lies far to the right”

Answer 12

the equilibrium greatly favors the products

Question 13

what generally happens to a reaction when the temperature increases

Answer 13

the reaction rate increases

Question 14

why does increasing the surface area of reactants or catalysts increase the rate of an reaction

Answer 14

it increases the likelihood of molecules encountering one another

Question 15

what occurs when an equilibrium is established in a reaction

Answer 15

The rate of the forward reaction is equal to the rate of the reverse reaction
