The significance of chemical reaction is
inevitable and there exist many kinds in real life. Recently, the concept of
quartic autocatalytic kind of chemical reaction was appraised (Refs.  –
). It is worth remarking that the concept had been wrongly used in a
recently published paper. To avoid confusion, this unpublished paper is
presented for clarification. In the report “entropy
optimization and quartic autocatalysis in MHD chemically reactive stagnation
point flow of Sisko nanomaterial, International Journal of Heat and Mass
”, the author investigated
cubic autocatalytic kind of chemical reaction between non-Newtonian Sisko fluid
and two molecules of catalyst situated at the surface. However, in three
different places including the title, the author claimed that the reaction is quartic autocatalysis.
