What is the need of catalyst poison?(a) Increase reaction(b) Increase

1.	What is the need of catalyst poison?(a) Increase reaction(b) Increase temperature(c) Decrease reaction(d) None of the mentionedThis question was addressed to me in an interview.This question is from Hydrogenation in division Hydrogenation of Unit Processes
Answer» Right choice is (c) Decrease reaction The best I can explain: Although absorption is closely related to the successful performance of a catalyst, it MAY RUIN an ACTIVE, catalyst, because other SUBSTANCES called catalyst POISONS may be so strongly retained by these active atoms that the substance being hydrogenated can no longer reach the active or catalytic areas.
