The reaction A to B follows first order kinetics. 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 mole of B ?

Answer»

1 hour
0.5 hour
0.25 hour
2 hours

Solution :(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.
