Question

For first order reaction a gives products the rate of reaction at a equals to 0.2 mole is 1 into 10 to the power minus 2 mole per litre per minute The Half Life Period of the reaction is

Answer 1

Let us considwer the problem:-

r=[A]

Implies that

k=

0.2

10

−2

=5.0×10

−2

Therefore

t
