Question

for a first order reaction A-->B reaction rate at reactant concentration 0.01M is found to be 2.0×10^-5MS^-1.the half life period of a reaction is​

Answer 1

Explanation:

$half \: life \: = \frac{ ln(2) }{k} \\ half \: life \: = \frac{ ln(2) }{2 \times {10}^{ - 5} } \\ half \: life \: = \: 34650s$

Answer 2

Answer:

halflife=

k

ln(2)

halflife=

2×10

−5

ln(2)

halflife=34650s
