Consider the reaction below. 2N205(9)+4NO2(9)+O2(9)
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.

This answer to this question is a rule that is applied to any reaction taken at dynamic equilibrium, with respect to 500 K. In other words, you can say that this reaction is of no use to us -

In a chemical equilibrium, it is known that the forward and reverse reactions occur at equal rates. At this point the concentrations of products and reactants remain constant, or in other words do not change

Solution = Option C

b. is the answer hoped i
