MHT CET Chemistry question
The following reaction , follows first order kinetics.
The time required for the conversion of 0.8 mol of A to 0.6 mol of B is 1hr.
What time would be required for the conversion of 0.9 mol of A to 0.675 mol of B ?
Answer: (C)
Solution
In both cases the fraction converted is 0.6/0.8 = 0.675/0.9 = 0.75, and for a first order reaction time depends only on the fraction converted,
