Question

4 moles each of SO2 and O2 gases are allowed to react to form SO3 in a closed vessel. At equilibrium, 25% of O2 is used Up. The total number of moles of all the gases at equilibrium is  

Solution

Correct option is

7.0

 

 

2 SO2  + O2      →         2 SO3

Initial moles   4            4                   0  

                       = 2 moles = 3

      ∴ Total no. of moles of all gases at eqm.

                            =2 + 3 + 2 = 7
