Question

In which of the following values of Kc the reaction goes to completion in the forward direction

Answer 1

Explanation:

Solution:- (A) K

c

=10

3

As we know that, reactions that go almost to completion have high equilibrium constants.

For a reaction, aR⇌bP

K

c

=

[R]

a

[P]

b

The larger value of equillibrium constant, (i.e.,K

c

≥10

3

), shows that reaction is favoured in forward direction, i.e., concentration of product is much larger than the concentration of reactant.

Hence, for K

c

=10

3

, the reaction go almost to completion.
