Question 1

Homogenous Equilibria

Answer 1

All products and reactants in the same state

Question 2

Heterogeneous Equilibria

Answer 2

Not all in the same state

Question 3

If Q=K

Answer 3

the reaction is at equilibrium

Question 4

Q is greater than K

Answer 4

The reaction will proceed to the left (reactants side, reverse reaction)

Question 5

Q is less than K

Answer 5

The reaction will proceed to the right (products side, forward reaction)

Question 6

Reactant Quotient

Answer 6

is the product of the product concentrations over the product of the reactant concentrations, with each concentration raised to a power equal to the corresponding stoichiometric coefficient in the balanced chemical equation.

Question 7

A large equilibrium constant (K>1) (>100)

Answer 7

indicates that products are favored at equilibrium

Question 8

A small equilibrium constant (K<1)(<0.01)

Answer 8

indicates that reactions are favored at equilibrium

Question 9

Le Châtelier’s Principle

Answer 9

A system at equilibrium will react to stress by shifting in the direction that will partially offset the effect of the stress
