Cоnsider the reаctiоn belоw with KC = 33.9 аt 25o C. H2 (g)+Cl2 (g) ⇌ 2HCl (g) The concentrаtion of H2 is measured to be 1.145 M, concentration of F2 is measured to be 1.145 M, and concentration of HF is measured to be 2.275 M. Which of the following is true regarding the above system? The reaction proceeds in the forward direction to reach equilibrium The reaction proceeds in the reverse direction to reach equilibrium The reaction is at equilibrium Therefore: 4. The concentration of the reactants will increase, and the concentration of the products will decrease. 5. The concentration of reactants and products will not change. 6. The concentration of products will increase, and the concentration of reactants will decrease.
