The reaction A `to`B follows first order reaction. The time taken for 0.8 mole of A to produce 0.6 mole of B is 1 hour. What is the time taken for conversion of 0.9 mole of A to produce 0.675 moles of B?

Options

A. 1 hour
B. 0.5 hour
C. 0.25 hour
D. 2 hours

Answer

A

Explanation

(a) : The freaction of A reacted in each case is same `(0.2//0.8=1//4),(0.9-0.675)//0.90=0.225//0.90=1//4)`. Hence, time taken is same.
