1.	Comment on the thermodynamic stability of NO(g) and NO_2(g) given : frac{1}{2}N_2(g)+frac{1}{2}O_2(g)rightarrowNO(g) , Delta_fH^o=90 kJ mol^-1 NO(g)+frac{1}{2}O_2(g)rightarrowNO_2(g) , Delta_fH^o=-74 kJ mol^-1
Answer» SOLUTION :SINCE energy is absorbed in the formation of NO, it is not very stable. Since energy is RELEASED in the second reaction, NO will be EASILY CONVERTED to the more stable `NO_2`.
