A first order reaction is carried out with an initial concentration of 10 mol per litre an 80% of the reactant changes into the product in 10 sec. Now if the same reaction is carried out with an initial concentration of 5 mol per litre. The percentage of the reactant changing to the product in 10 sec is:

A

40

B

80

C

60

D

50

Text Solution

Verified by Experts

The correct Answer is:
B
`10M(80%)/(t=10"sec")2M 5M(80%)/(t=10"sec")1M`
