At 600 K , 2 mol of NO are mixed with 1 mol of O 2 . 2 NO g + O 2 g ⇄ 2 NO 2 g The reaction occurring as above comes to equilibrium under a total pressure of 1 atm. Analysis of the system shows that 0 . 6 mol of oxygen are present at equilibrium. The equilibrium constant for the reaction is____.

Step-by-step solution

2 NO     +       O 2 →         2 NO 2       1                   - 2 - 2 x         1 - x               2 x 1 . 2       0 . 6                 0 . 8 Total number of moles= 2 . 6 According to Dalton's law, Partial pressure = Total pressure × Mole fraction Mole fraction = Number   of &#160
