TS EAMCET · Chemistry · Chemical Equilibrium
Which one of the following is correct?
- A The equilibrium constant \(\left(K_c\right)\) is independent of temperature
- B The value of \(K_c\) is independent of initial concentrations of reactants and products
- C At equilibrium, the rate of the forward reaction is twice the rate of the backward reaction
- D The equilibrium constant \(\left(K_c\right)\) for the reaction \(\mathrm{Ni}(s)+4 \mathrm{CO}(g) \rightleftharpoons \mathrm{Ni}(\mathrm{CO})_4(g) \text { is, } \frac{\left[\mathrm{Ni}(\mathrm{CO})_4\right]}{[\mathrm{CO}]}\)
Answer & Solution
Correct Answer
(B) The value of \(K_c\) is independent of initial concentrations of reactants and products
Step-by-step Solution
Detailed explanation
Correct option is (b) as (a), (c) and (d) are false. (a) \(K_c\) depends on temperature. (c) At equilibrium, both the rates are equal. (d) \(K_c=\frac{\left[\mathrm{Ni}(\mathrm{CO})_4\right]}{[\mathrm{CO}]^4}\)
