**6. Validation of the Results**

Comparison between present and previous outcomes for justification is given in this section. Table 1 delineated to certify the accuracy of our current outcome with an available outcome in literature. The comparison of concentration gradient *Shx*Re*<sup>x</sup>* <sup>−</sup>1/2 with variation of *Sc* while the rest of the parameters are associated with Ref. [21] and shown in Table 1. Obviously the outcome is in acceptable understanding.

**Table 1.** Numerical variation of mass transfer rate *Shx* and their comparison with Ref. [21] via various value of *Sc* at *Gr* = *n* = 0.1, *Nr* = 0.5.
