The reaction below is at dynamic equilibrium. Upper N subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). Which statement is true for the equilibrium system?

Explanation:

The answer choices for this question are:

The described equation is:

A dynamic equilibrium means that there is not change of the concentrations of the species but yet the forward and the reverse reactions are occurring.

The condition for a dynamic equilibrium is that both the rate of the forward and the rate of the reverse reaction are equal.

Thus, the third choice "The rate of the forward reaction equals the rate of the reverse reaction" is the correct one.

You cannot compare the concentrations of products and reactants since that depends on the initial concentrations and the equilibrium constant.

If the equilibrium constant is greater than 1 then the substances on the right are favored, if the equilibrium constatn is less than 1 then the substances of the left are favored. But you cannot tell which concentration is greater a priori.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
