Question
1N For the gas-phase chemical reaction A+B«C+ 2D the equilibrium constant expression for reaction is (C]D]? K 15.9 atm at 400°C. [ A][B] A reaction mixture is prepared in which the initial concentrations are [A] = | atm, [B] = 2 atm, [C] = 0, [D] = 0. From mass balance and stoichiometry, the concentrations at equilibrium are (A] = 1 -- x, [B] = 2 – x, [C] = x, [D]= 4x3 2x, from which the expression for K is- Find the value of x that x2 - 3х + 2 makes the expression have a value of 15.9, and calculate the partial pressures of A, B, C and D at equilibrium.
