| (i) The numerical value of the equilibrium constant for a reaction indicates the extent of the reaction. |
| (ii) An equilibrium constant give information about the rate at which the equilibrium is reached. |
| (iii) If \[{{K}_{c}}>{{10}^{3}},\] products predominate over reactants, i.e., if \[{{K}_{c}}\] is very large, the reaction proceeds nearly to completion. |
| (iv) If \[{{K}_{c}}<{{10}^{-3}},\] reactants predominate over products, i.e., if \[{{K}_{c}}\] is very small, the reaction proceeds rarely. |
A) (i), (ii) and (iv) are correct
B) (i), (iii) and (iv)
C) (i), (ii) and (iii) are correct
D) only (iii) is correct
Correct Answer: B
Solution :
[b] An equilibrium constant does not give any information about the rate at which the equilibrium is reached.
