Question

Select all of the correct statements about equilibrium from the choices below.

A. At equilibrium the rates of forward and reverse reactions are equal.



B. As a reaction proceeds forward toward equilibrium the forward rate drops.



C. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise.



D. As a reaction proceeds forward toward equilibrium the reverse rate rises.



E. At equilibrium the forward rate equals the reverse rate.



F. As a reaction proceeds forward toward equilibrium the forward rate constant drops.

I had selected A, B, D, E, F and it was not right Please Help!

Explanation / Answer

Lets explain it for all the options.

A). Equilibrium state is the one in which all concentrations remains same and that is explained by another way, rate of product formation and rate of reactant formation from product is same so the first statement is correct.

B). When reaction tries to go the equilibrium in forward direction then the rate of forward direction is more than that of backward direction so this statement is not correct.

C).

When reactions goes to the backward direction then the rate of revers reaction is more and so formation of reactant in this case more so their concentration rise.

This statement is correct.

D).

When reaction proceed forward in order to achieve equilibrium then its reverse rate decrease. So this statement is not correct.

E)

This is correct statement.

F)

When reaction proceed to the forward then rate constant of the forward reaction increase.

So the correct statements are

A, C,E,F
