What is the reaction quotient?

A. It measures the [products] / [reactants]

B. It measures the concentration of the reactants.

C. It measures the concentration of the products.

D. It measures the [reactants] / [products]

Reset

A. It measures the [products] / [reactants].

Explanation:

The reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products. It is calculated from the concentration of the products and reactants at mixing up. Reaction quotient (Q) = [products] / [reactants]

So, the right choice answer:

A. It measures the [products] / [reactants].
