One mole \(\mathrm{H}_2 \mathrm{O}(\mathrm{g})\) and one mole \(\mathrm{CO}(\mathrm{g})\) are taken in \(1 \mathrm{~L}\) flask and heated to \(725 \mathrm{~K}\). At equilibrium, \(40 \%\) (by mass) of water reacted with \(\mathrm{CO}(\mathrm{g})\) as follows.
\(\mathrm{H}_2 \mathrm{O}(\mathrm{g})+\mathrm{CO}(\mathrm{g}) \rightleftharpoons \mathrm{H}_2(\mathrm{~g})+\mathrm{CO}_2(\mathrm{~g})\)
Its \(K_p\) value is

  1. A \(2.220\)
  2. B \(0.444\)
  3. C \(4.440\)
  4. D \(0.222\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(0.444\)

Step-by-step Solution

Detailed explanation

\begin{aligned} & \text { (b) } \mathrm{K}_{\mathrm{p}}=\mathrm{K}_{\mathrm{c}}(\mathrm{RT})^{\Delta \mathrm{n}_{\mathrm{g}}} \\ & \mathrm{H}_2 \mathrm{O}(\mathrm{g})+\mathrm{CO}(\mathrm{g}) \rightleftharpoons \mathrm{H}_2(\mathrm{~g})+\mathrm{CO}_2(\mathrm{~g}) \\ & \Rightarrow…
