**6. Conclusions**

Lastly, the influence of a chemical reaction parameter on the concentration profiles is depict‐ ed in **Figure 15**. Physically, the concentration profiles decreases as the chemical reaction

The problem of MHD micropolar fluid, heat and mass transfer over unsteadiness stretching sheet through porous medium in the presence of a heat source/sink and chemical reaction is Stanford Shateyi1\*, Fazle Mabood2 and Gerald Tendayi Marewo3
