At a certain temperature, equilibrium constant `(K_(c))` is `16` for the reaction:
`SO_(2)(g)+NO_(2)(g) hArr SO_(3)(g)+NO(g)`
If we take `1` mol of each of the four gases in a `1L` container, what would be the equilibrium concentrations of NO and `NO_(2)`?

Text Solution

Verified by Experts

`SO_(2)(g) + NO_(2)(g) rarr SO_(3)(g) + NO(g)`
`Qc = 1 < Kc`, i. e. reaction proceed in forward direction to attain equilibrium
`16 = (x/1-x)^(2) implies x = 0.60`
`[NO]=1.60M , [NO_(2)] = 0.40 M`
