Consider the reaction: 2NO(g)+O(2)(g) ...

Consider the reaction:
`2NO(g)+O_(2)(g) rarr 2NO_(2)(g)`
Calculated the standard Gibbs energy change at `298K` and predict whther the rection is spontaneous or not. `Delta_(f)G^(Theta) (NO) = 86.69 kJ mol^(-1), Delta_(f)G^(Theta) (NO_(2)) = 51.84 kJ mol^(-1)`.

Text Solution

Verified by Experts

`DeltaG^(Theta) = 2 Delta_(f)G^(Theta) (NO_(2)) -2 [Delta_(f)G^(Theta) (NO)+Delta_(f)G^(Theta) (O_(2))]`
`= 2 xx 51.84 -2 xx 86.69 -0 =- 69.7 kJ mol^(-1)`
