Yes and no.
Yes, you have the right answer.
No, k is not 225. t1/2 is 225.
k = 0.693/t1/2
k = 0.693/225 = 3.08E-3
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?
