Consider the following reaction: NH4HS(s)?NH3(g)+H2S(g)An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]= 0.272M and [H2S]= 0.360M .What is the value of the equilibrium constant (Kc) at this temperature?2) The reaction in Example 14.12 is carried out at the same temperature with the following initial concentrations: [H2S] = 0.100 M, [H2] = 0.100 M, and [S2] = 0.00 M. Find the equilibrium concentration of [S2].3) The reaction CO2(g)+C(s)?2CO(g) has Kp=5.78 at 1200 K. Part A: Calculate the total pressure at equilibrium when 4.56g of CO2 is introduced into a 10.0-L container and heated to 1200 K in the presence of 2.19g of graphite. Part B: Repeat the calculation of part A in the presence of 0.31g of graphite.
