At 298 K, `K_(p)` for the reaction : `N_(2)O_(4)(g) iff 2NO_(2)(g)` is 0.98. Predict whether the reaction is spontaneous or not.

Explanation

For the reaction, `N_(2)O_(4) (g) hArr 2NO_(2) (g), L_(P) = 0.98`
As we know that `Delta_(r) G^(Θ) = - 2.303 RT log K_(P)`
Here, `K_(P) = 0.98` i.e., `K_(P) lt 1` therefore, `Delta_(r) G^(@)` is positive, hence the reaction is non-spontaneous.
