Question

Acetic acid + Ethanol <=> Ethylacetate + water Equilibrium occurs when

Concentrations are at a minimum but not equal

There is an equivalent amount of products to reactants

the reaction stops and K(forward) equals 1/K(reverse)

the rate forward equals the inverse of the reverse rate

There is no net change in concentrations

Answer 1

A)

this statement is false

concentrations may or may not be equal

B)

this is also false

because

products to reactants are not equivalent

C)

this statement is false

because the reaction does not stop

D)

this statement is false

because

we know that

equilibrium occurs when

rate of forward reaction is equal to rate of reverse reaction

E)

this statement is true

because

at equilibrium

the reaction still continues

only

there is no net change in concentrations

So

the answer is no net change in concentrations
