Question 1

what are the 4 factors that effect the position of equilibrium

Answer 1

1. concentration of a component
2. the pressure of a system
3. temperature of a system
4. addition of a catalyst

Question 2

if we increase the concentration of the reactants

Answer 2

the rate if the forward reaction would increase the concentration of the product, causing an increase in the backward reaction with equilibrium reached in another position with in shifted to the right

Question 3

if we decrease the concentration of the reactants the equilibrium is shifted to the

Answer 3

left

Question 4

if we increase the concentration of the reactants the equilibrium is shifted to the

Answer 4

right

Question 5

if we increase the concentration of the products the equilibrium is shifted to the

Answer 5

left

Question 6

if we decrease the concentration of the products the equilibrium is shifted to the

Answer 6

right

Question 7

a change of pressure in reversible reaction only effects

Answer 7

reaction involving gas

Question 8

the pressure of a gaseous mixture depends on

Answer 8

the number of gas molecules in a given volume

Question 9

we can increase the pressure by

Answer 9

reducing the volume or by using more moles of reactants in the same volume

Question 10

we can decrease the pressure by

Answer 10

increasing the volume or by using fower moles of reactant in the same volume

Question 11

if we increase the pressure and the moles of the reactant is more the equilibrium shifts to the

Answer 11

right

Question 12

if we increase the pressure and the moles of the reactant is less the equilibrium shifts to the

Answer 12

left

Question 13

if we increase the pressure and the moles of the reactant are the same as the products the equilibrium shifts to the

Answer 13

nowhere in stays the same trick question haha

Question 14

if the forward reaction is exothermic and we increase the temperature the equilibrium would shift

Answer 14

to the left

Question 15

if the forward reaction is endothermic and we increase the temperature the equilibrium would shift

Answer 15

the the right

Question 16

if we add a catalyst what will happen

Answer 16

the rate of both the forward and backward reaction increases but at the same rate so the equilibrium doesn’t shift

Question 17

if you increase or decrease the temperature what will happen

Answer 17

both the forward and the backward reaction would increase but one will increase further
