Comment on the thermodynamic stability of NO(g) ,given (1)/(2)N_(2)(g)

1.	Comment on the thermodynamic stability of NO(g) ,given (1)/(2)N_(2)(g)+(1)/(2)O_(2)(g) rarr NO(g) , Delta_(r)H^(@) =90kJ mol^(-1) NO(g)+(1)/(2)O_(2)(g) rarrNO_(2)(g) , Delta_(r)H^(@) =- 74kJ mol^(-1)
Answer» SOLUTION :As energy is ABSORBED in the first reaction`NO(g)` is UNSTABLE. As energy is released in the second reaction, `NO_(2)(g)` is STABLE. Thus, unstalbe `NO(g)` changes into the stable `NO_(2)(g)`
