1.	In heterogeneous reaction, if a reaction proceeds slowly even in the presence of adequate substrate then mass transfer will be?(a) Slow(b) Very slow(c) Rapid(d) NegligibleThe question was asked in an online quiz.This question is from Concentration Gradients and Reaction Rates in Solid Catalysts topic in division Heterogenous Reactions of Bioprocess Engineering
Answer» Correct option is (c) RAPID To explain I would say: If a reaction PROCEEDS slowly even in the presence of adequate substrate, it is likely that mass transfer will be rapid enough to meet the reaction demand. In this case, the observed rate would be determined more directly by the reaction PROCESS than mass transfer. Conversely, if the reaction TENDS to be very rapid, it is likely that mass transfer will be too SLOW to supply substrate at the rate required.
