Consider the reaction below. 2 cap n sub 2 cap o sub 5 g long left right arrow 4 cap n cap o sub 2 g plus cap o sub 2 times g If the reaction is at dynamic equilibrium at 500 cap k , which statement applies to the given chemical system?
Answer
A
The rates of the forward and reverse reactions are unequal.
B
The concentrations of the products and reactants do not change.
C
The forward reaction stops at 500 cap k .
D
The forward and reverse reactions no longer occur.
Explanation
At dynamic equilibrium, the forward and reverse reactions continue at equal rates. Because each reaction uses and forms substances at the same rate, the concentrations of the reactants and products do not change over time. The reactions do not stop; they remain active at 500 K.
