At 298 K, K(p) for the reaction : N(2)O(...

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.

Text Solution

Verified by Experts

`Delta_(r) G^(@) = - RTln K_(p)`. Here , `K_(p)= 0.98`, therefore, `Delta_(r)G^(@) ` is`-ve`. Hence, the reaction is spontaneous.
