Question

In the reaction NO + NO2 ⇌ N2O3, an experiment finds equilibrium concentrations of [NO] = 3.8 M, [NO2] = 3.9 M, and [N2O3] = 1.3 M. What is the equilibrium constant Kc for this reaction?

Answer 1

Answer: The equilibrium constant
`K_c` for this reaction is 0.088

Step-by-step explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
`K_c`

For the given chemical reaction:

`NO+NO_2(g)\rightarrow N_2O_3`

The expression for
`K_c` is written as:

`K_c=([N_2O_3])/([NO_2][NO])`

`K_c=((1.3))/((3.9)* (3.8))`

`K_c=0.088`

The equilibrium constant
`K_c` for this reaction is 0.088
