Question

For the reversible system X(g)===== y(g) + z(g) a quantity X was heated at constant pressure P at a certain
temperature. The equilibrium partial pressure of X was found to be P/7. What is value of Kp at the given
temperature,
6р/7
9P/7
36P/7
6P​

Answer 1

Answer:

6p is correct answer........I hope.......

Answer 2

The value of Kp = $\frac{36P}{7}$

Explanation:

                            X(g) ⇄ Y(g) + Z(g)

Initial                     p          0        0

At equilibrium    p - a       a        a

Given that  Partial pressure of

                        X = $\frac{P}{7}$

      ⇒          p - a = $\frac{P}{7}$

      ⇒               a = $\frac{6P}{7}$

      Partial pressure of Y = $\frac{6P}{7}$  and for Z = $\frac{6P}{7}$

     Partial pressure of X =  $\frac{P}{7}$

                    ⇒    Kp = $\frac{P_{Y}XP_{Z} }{P_{X} }$

                   ⇒   Kp = $\frac{\frac{6P}{7} X\frac{6P}{7} }{\frac{P}{7} }$

                   ⇒    Kp = $\frac{36P}{7}$
