Norma-Jean [14]

Answer:

The correct answer is reaction will achieve equilibrium by forming more products and will move in left to right direction.

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • If Q > K_{eq}  , then the equilibrium will shift in left direction or in backward direction.the reaction will move back to the formation of reactants from the product
  • If Q < K_{eq}  , then the equilibrium will shift in right direction or in forward direction.The reaction will form more products
