Chemical reactions and catalysis MCQ - Practice Questions with Answers

An autocatalysed reaction is one in which a product of the reaction acts as the catalyst and increases the reaction rate as more of it forms. A reversible reaction is defined by forward and backward change, not by a product acting as a catalyst. A biochemical reaction occurs in living systems or involves biomolecules, which is a different basis of classification. A displacement reaction involves one element or group replacing another. The clue in the stem is the product catalysing the reaction, so the correct term is autocatalysed.
