$248.$In case of absorption with exothermic reaction, for fluids having

Pr $=$ Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence

Pr $=$ Sc $=1$; total mass, momentum and thermal diffusivity will be the same

Both $($A$)$ and $($B$)$

Pr $=$ Sc; there won't be any change in heat and mass transfer flux with changes in degree of turbulence
