NEET 2011 Chemistry question
The half life of a substance in a certain enzyme-catalysed reaction is 138 s. The time required for the concentration of the substance to fall from to , is :
Answer: (3)
Solution
The enzyme-catalysed reaction is treated as first order in the substrate, so each half-life halves the concentration irrespective of the starting value. Ratio of concentrations = 1.28/0.04
