Question

for the reaction take place at certain temperature NH2COONH4 (s)= 2NH3 (g)+ CO2 (g) . if equilibrium pressure is 3X bar then then change in standard gibbons free energy is

Answer 1

 
  If the eqm pressure is 3 atm the partial pressure of NH3 is 2 atm and the partial pressure of CO2 1atm 

and 

Kp = 2^2 x 1 = 4
