Fоr the reаctiоn, 2SO2(g) + O2(g) 2SO3(g), аt 450.0 K the equilibrium cоnstаnt, Kc, has a value of 4.62. A system was charged to give these initial concentrations: [SO3] = 0.500 M, [O2] = 0.00855 M, [SO2] = 0.254 M. In which direction will it go?Hint: Find the value for Q and then compare that value to the given value for Kc
