What are the roots for x in this quadratic equation? 2 x2 - 7 x + 0.5 = 0 The larger root is (use 3 significant figs) The smaller root is (use 3 significant figs) Now calculate the equilibrium concentration of reactant A. In the ICE table the equation for the concentration of reactant A in the equilibrium row is [A] = 0.5 - 2x [A] = M at equilibrium.
After equilibrium is reached, (X)=.55 M. Calculate the Keq (Kc) for this reaction. show full steps please for rating
