2SO2(g) + O2(g) = 2SO3(g) For this exothermic reaction, the equilibrium constant, K = 781. If, after equilibrium has been reached, the non-reacting element Ar (g) is added without changing the volume or temperature the result will be: Select one: the reaction will shift in the forward direction the reaction will shift in the backward direction unpredictable no change in reaction mixture
The following system was allowed to come to equilibrium at 300 K. H₂(g) + X₂(g) → 2HX(g) The system was initially charged with 0.334 M H₂, 0.334 M X₂ and 1.65 M HX. Determine the value of K at 300K. Select one: 24.4 14.8 0.0410 29.8
The equilibrium constant, Kċ, for the following system is 4.62. 2SO₂(g) + O₂(g) ⇒ 2SO3(g) A system was prepared to give these initial concentrations, [SO3] = 0.500 M [O₂] = 0.00855 M, [SO₂] = 0.254 M. In which direction will the reaction go? Select one: To the left To the right It depends on the pressure of the system The equilibrium position will remain the same
