ANSWER
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.
Answer: (b) 10³
Explanation: Bcz the value of kc icreases as the reaction goes to completion so here (b) is correct option
