NH4CN(a solid) is warmed in a chamber and the following reaction occurs NH4CN (s)→HCN(g)+NH3(g) When the reaction chamber initially containing only NH4CN is warmed the pressure of HCN was found to be 0.6 atm.
a. Write down the equilibrium expression Kp for this reaction.
b. Based on the information provided, determine the value of Kp.
