The equilibrium constant for the reaction NO2(g)+NO3(g)→N2O5(g) is 2.1x10-20 , therefore: a. At equilibrium, the concentration

frutty [35]

Answer: c. At equilibrium, the concentration of reactants is greater than the products

Explanation:

Equilibrium constant for a reaction is the ratio of concentration of products to the concentration of reactants each raised to the power its stoichiometric coefficients.

For the reaction:

$NO_2(g)+NO_3(g)\rightleftharpoons N_2O_5(g)$

Equilibrium constant is given as:

$K_{eq}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}$

$2.1\times 10^{-20}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}$

When

a) K > 1, the concentration of products is greater than the concentration of reactants

b) K < 1, the concentration of reactants is greater than the concentration of products

c) K= 1, the reaction is at equilibrium, the concentration of reactants is equal to the concentration of products

Thus as $K_{eq}$ is $2.1\times 10^{-20}$ which is less than 1,

the concentration of reactants is greater than the concentration of products
