Question

which of the following describes a reaction with a very fast rate of reaction and a small k value? slowly moves to an equilibrium ratio of a lot of products and a few reactants very quickly moves to an equilibrium ratio of all products very quickly moves to an equilibrium ratio of a few products and lots of reactants slowly moves to an equilibrium ratio of a few products and lots of reactants

Explanation:

The rate of a reaction refers to how quickly it proceeds to equilibrium. A fast - rate reaction reaches equilibrium rapidly. The equilibrium constant $K$ is the ratio of product concentrations to reactant concentrations at equilibrium. A small $K$ value means that at equilibrium, there are more reactants than products. So a reaction with a fast rate and small $K$ value quickly reaches an equilibrium with few products and many reactants.

Answer:

Very quickly moves to an equilibrium ratio of a few products and lots of reactants
