MISSED THIS? Read Section 16.8 (Pages 701 - 710); Watch KCV 16.8, IWE 16.9. Consider the following reaction and associated equilibrium constant: aA(g) =bB(g), Ke-2.9 = Equilibrium 1.0-2r 2x Substitute the expressions for the equilibrium concentrations into the expression for the equilibrium constant and use the given value of the equilibrium constant: Solving the expression for the variable gives Part C IVLI ΑΣΦ [A] =0.58,0.84 0.32 Substitute into the expressions for the equilibrium concentrations of A and B and calculate the concentrations: 2(0.32 M) = 0.63 M B = [A] = 1.0 M-2(0.32 M) = 0.37 M Submit Previous Answers Request Answer X Incorrect; Try Again Ke = 2.9 2x 1.0 - 2x Provide Feedback = Find the equilibrium concentrations of A and B for a = 1 and b = 2 . Assume that the initial concentration of A is 1.0 M and that no B is present at the beginning of the reaction. Express your answers in molarity to two significant figures separated by a comma. = ² [A]² ? (2x)² (1.0-2x)² M Next >
