Answer 1

Answer #1

Delta h negative means more bond are form than no of bond broken during the reaction. Because delta degative energy is release during the reaction thats why more bond are form.

Delta s is negative means randmnesss of system is decrease is may be decrease due to cyclization or any other effect. Or we can say entrpy decrease means no of reacting species or than the forming.

Thank you have a nice day
