TS EAMCET · Chemistry · Chemical Equilibrium
For the given equilibrium reaction \(\mathrm{H}_2(g)+\mathrm{I}_2(g) \rightleftharpoons 2 \mathrm{HI}(g)\) Choose the correct equation to calculate \(K_p\).
- A \(K_p=K_C\)
- B \(K_p=K_C(R T)\)
- C \(K_p=K_C(R T)\)
- D \(K_p=K_C(R T)^2\)
Answer & Solution
Correct Answer
(A) \(K_p=K_C\)
Step-by-step Solution
Detailed explanation
We know, \(K_p=K_C(R T)^{\Delta n_g}\) For the given equilibrium reaction, \(\begin{aligned} & \mathrm{H}_2(g)+\mathrm{I}_2(g) \rightleftharpoons 2 \mathrm{HI}(g), \Delta n_g=2-(\mathrm{l}+\mathrm{l})=0 \\ \Rightarrow & K_p=K_C \times(R T)^0=K_C \end{aligned}\)
