Q1. The reaction which is catalysed by the product formed is called a _________ reaction.
A reversible
B autocatalysed Correct
C biochemical
D displacement
Explanation
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.
