Question

For the reaction

NH₂COONH_4(s) ⇋ 2NH₃(_g) + CO_2(g)  

The equilibrium constant K_p = 2.9 x 10^-5 atm . The total pressure of gases at equilibrium when 1.0 mole of reactant was heated will be :

(A) 0.0194 atm 

(B) 0.0388 atm 

(C) 0.0580 atm 

(D) 0.0667 atm

Answer 1

Correct option (C) 0.0580 atm 

Explanation : 

total moles of gaseous substances at equilibrium = 3x

equilibrium pressure = p
