Question

Consider the reaction below. 2 upper N subscript 2 upper O subscript 5 (g) double-headed arrow 4 upper N upper O subscript 2 (g) plus upper o subscript 2 (g).

Answer 1

c

Step-by-step explanation:

Answer 2

The concentrations of the products and reactants do not change.

Step-by-step explanation:

The following information is missing:

If the reaction is at dynamic equilibrium at 500 K, which statement applies to the given chemical system?

• The forward and reverse reactions no longer occur.

• The rates of the forward and reverse reactions are unequal.

• The concentrations of the products and reactants do not change.

• The forward reaction stops at 500 K.

Dynamic equilibrium means that the rate of the forward and reverse reactions are equal and different from zero. Then, the concentrations of the products and reactants do not change.
