3. Consider the following equilibrium reaction: NH4SH(s)NH3(g)+H2S(g)Kp=0.781at25C (a) Write the expression for Kp. Kp= Use "ICE" tables to work the following parts. (MW of NH4SH=51g/mol ) (b) A 5.00g sample of NH4SH is introduced into an empty 1.60L flask at 25C. What will be the total gas pressure after equilibrium is established? NH4SH(s)NH3(g)+H2S(g) Initial: Change: Equilibriium: Final total pressure (atm): (c) A 5.00g sample of NH4SH is introduced into an empty 3.50L flask at 25C. What will be the total gas pressure after equilibrium is established
