how do we determine if a reaction is at e\nq = products/reactants\n15) what does (q) represent in the mathematical equation?\n16) if q = k:\na) the reaction must shift to the right, producing more products.\nb) the reaction must shift to the left, producing more reactants.\nc) the reaction is already in a dynamic equilibrium.

Answer

Brief Explanations:

  1. In the context of chemical - reactions, Q is the reaction quotient. It is a measure of the relative amounts of products and reactants present during a reaction at a particular point in time.
  2. In chemical equilibrium, K is the equilibrium constant. When Q = K, the forward and reverse reaction rates are equal, indicating that the reaction is in a state of dynamic equilibrium.

Answer:

  1. The reaction quotient, which is the ratio of the concentrations (or partial pressures for gas - phase reactions) of products to reactants at a given moment in the reaction.
  2. C) The reaction is already in a dynamic equilibrium.
