The following pertain to chemical reactions. (a) Write down the quotients Q for the following reactions: N_2 + 3H_2 rightarrow 2NH_3, CO + 2H_2 rightarrow CH_3OH, 2 NO + O_2 rightarrow 2 NO_2. (b) Consider the reactions CO + H_2O rightarrow CO_2 + H_2, and CH_4 + H_2O rightarrow CO + 3H_2 The equilibrium constant for the first reaction is K_1 = 1.4 and for the second K_2 = 5.3 times 10^-3 M^2. Here M is the common unit of concentration in chemistry M = mol/1 = kmol/m^3. What is the equilibrium constant for the reaction CH_4 + 2H_2O rightarrow CO_2 + 4H_2? (c) Assume that the following reaction, 2 H_2S + CH_4 rightarrow 4H_2 + CS_2, has an equilibrium constant K = 4.56, where the unit is an appropriate power of M Given the following equilibrium concentrations: nH_2s = 0.15 M, nCH_4 = 0.56 M, and n_CS_2 = 0.37 M, What is the equilibrium concentration of H_2?
