Question
The reaction A → B follows first order kinetics. The time taken for 0.8 mol of A to produce 0.6 mol of B is 1 hr. What is the time taken for the conversion of 0.9 mol of A to product 0.675 mol of B ?
Options
A.1 hr
B.0.5 hr
C.0.25 hr
D.2 hr
Solution
Time for the conversion of 0.8 mol of A to 0.6 mol of
B =
= 0.75 = t75%
Similarly, time for the conversion of 0.9 mol of A to 0.675 mol of
B =
= 0.75 = t75%
Hence, t75% in both case = 1 hr
B =
= 0.75 = t75%Similarly, time for the conversion of 0.9 mol of A to 0.675 mol of
B =
= 0.75 = t75%Hence, t75% in both case = 1 hr
