When solid (NH4)(NH2CO2) is introduced into an evacuated flask at 25 ∘C, the total pressure of gas at equilibrium is 0.116 atm. What is the value of Kp at 25 ∘C? Kp =

Answer : The value of is,

Explanation :

For the given chemical reaction:

The expression of for above reaction follows:

       ........(1)

Initial:                                                      0               0

At eqm:                                                   2x              x

As we are given that:

Total pressure of gas at equilibrium = 0.116 atm

2x + x = 0.116 atm

3x = 0.116 atm

x = 0.0387 atm

Putting values in expression 1, we get:

Thus, the value of is,
