At 1990   K and 1   atm pressure, there are equal number of Cl 2 molecules and Cl atoms in the reaction mixture. The value of K p for the reaction Cl 2 g = 2 Cl g under the above conditions is x × 10 - 1 . The value of x is______(Rounded off to the nearest integer)
Correct answer
0
Step-by-step solution
Cl 2 ⇌ 2 Cl Let mol of both of Cl 2 and Cl is x P Cl = x 2 x × 1 = 1 2   atm P Cl 2 = x 2 x × 1 = 1 2   atm K p = 1 2 2 1 2 = 1 2 = 0 . 5 ⇒ 5 × 10 - 1
