Comment on “Effects of homogeneous-heterogeneous reactions in flow of magnetite-Fe3O4 nanoparticles by a rotating disk, Tasawar Hayat, Maria Imtiaz, Ahmed Alsaedi, Faris Alzahrani, Journal of Molecular Liquids 216 (2016) 845-855”

- The problem concerns flow of a nanofluid near in a rotating disk.
- The term Trz−T∞Tw−T∞ is not compatible with the term θ(η).
- The parameters Ec and Re are not suitable for a correct solution.
