Which of the following statements about the reaction quotient, Q is false? a. The value of Q can be used to predict equilibrium
irakobra [83]

Answer:

The correct statements are :b, c , d, and e.

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 equilibrium quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • Q_c, reaction will move in forward direction and concentration of products will increase.
  • Q_c>K_c, reaction will move in backward direction and concentration of reactant will increase.
  • Q_c=K_c reaction is at equilibrium.

You were making a cream based sauce for your pasta and decided to add some freshly canned tomatoes to the sauce. It tasted fine,
soldier1979 [14.2K]

Answer & explanation:

Canned fruits and vegetables generally have a high acidity and salinity content, in order to prevent the product from spoiling, in addition to enhancing its flavor.

The cream-based sauce started to curdle due to the acidity present in the canned tomatoes.

By lowering the pH of dairy products, a protein in them called casein begins to clot. It is this clotting of the casein that causes the cream-based sauce to curdle.
