Equalibria

Question 1

What is equilibrium?

Answer 1

The equalization of reactants and products produced in a reversible reaction (Like if people were in a room and every time someone leaves, another enters)

Question 2

Features of Dynamic Equilibrium

Answer 2

1. Forward + Backwards reactions occur at the same rate
2. The concentration of reactants and products stay consistent

Question 3

Dynamic in equilibrium means?

Answer 3

Both forward and backward reactions at the same time

Question 4

Position of equilibrium means?

Answer 4

Describing the composition of the equilibrium mixture.
If the position of equilibrium favours the reactants, then the equilibrium mixture will contain mostly reactants.

Question 5

What external features would effect equilibrium?

Answer 5

Temperature, Pressure, and Concentration

Question 6

Effect of temperature on equilibrium?

Answer 6

Temp increase = Opposition by moving to endothermic (Cooler) side and producing more of that

Temp decrease = Opposition by moving to exothermic (Warmer) side and producing more of that

Question 7

What effect would increasing temperature have on the yield of ammonia?
N2 + 3H2 2NH3 H = -ve exo

Answer 7

The position of equilibrium will shift towards the left, giving a lower yield of ammonia. (-ve exo means temp is increased, so it’ll go to the opposite direction)

Question 8

Effects of pressure on equilibrium?

Answer 8

More pressure = Opposition by shifting to side with the least amount of moles (Least total of coefficients on that side)

Less pressure = Opposition by shifting to side with the most amount of moles (Most total of coefficients on that side)

Question 9

What happens if the number or moles (coefficients) is the same on both sides?

Answer 9

Equilibrium doesn’t shift with any pressure change

Question 10

What effect would increased pressure have on methanol?

CO + 2H2<===> CH3OH

Answer 10

The position of equilibrium will shift towards the right because there are three moles in total of CO and H2 versus only one mole of CH3OH, producing more moles of menthol to equal it out

Question 11

How to remember equilibrium reactions easier (for me)

Answer 11

20 people in room analogy (One person leaves another enters at the same time)

Question 12

Equilibrium constant (K)

Answer 12

Ratio of products to reactants at equilibrium

Question 13

K = ? (Formula)

Answer 13

K = Products/Reactants (Or K = [C] ^ x + [D]^y / [A]^ z + [B] ^ f)
