Question 1
2SO2(g)+O2(g) ⇌ 2SO3(g) + Heat
Increasing the temperature will...
shift equilibrium right
shift equilibrium left
increase pressure
have no change
Question 2
Heat + 1 N2O4 → 2 NO2
OR
What will happen when the temperature is increased?
Position of equilibrium will shift to left and become lighter in color
Position of equilibrium will shift to right and become more brown
No change in position of equilibrium
Position of equilibrium will shift to right and become lighter in color
Question 3
CoCI42- +6H2O →Co(H2O)62+ + 4CI- + Heat
OR
What will happen when the temperature is increased?
Position of equilibrium will shift to left and become more blue
Position of equilibrium will shift to right and become more pink
No change in position of equilibrium
Position of equilibrium will shift to left and become more pink
Question 4
It shifts left, towards the reactants
It shifts right, towards the products
It does not shift
Question 5
The following factors affect the position of equilibrium EXCEPT
Concentration
Pressure
Temperature
States of matter
Question 6
If a reversible reaction is exothermic in the forward direction, it will be ...
exothermic in the reverse direction
endothermic in the forward direction too
endothermic in the reverse direction
not involve energy in reverse direction
Question 7
Increase in temperature of the reactants can do one of the following
Slow collision frequency
Allow less effective collision between the particles
Cause particles to lose speed
Increase collision between the particles thus increasing the rate.
