Question

The rate constant of a first-order process that has a half-life of 225 s is ?????? s-1.

ok so i divided

half life of 1st order= 0.693/K

k i put 225

and i got 3.08 x 10^-3
is that right?

Yes and no.
Yes, you have the right answer.
No, k is not 225. t<sub>1/2</sub> is 225.
k = 0.693/t<sub>1/2</sub>
k = 0.693/225 = 3.08E-3
