Achemical reaction is at equilibrium. what will be the effect if more of the product is added? question 10 options: the reaction will shift to the right (toward the products). the reaction will shift to the left (toward the reactants). there will be no effect; the reaction will stay at equilibrium.

The answer is the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
      Reactants ⇄ products

After coming to the equilibrium, if one condition is changed, then according to the Le chatelier's Principal, the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.

Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
