Thank you for posting your question here at . I hope the answer will help you. Feel free to ask more questions.
Determine the reaction order, the rate constant, and the units of the rate constant.
0th order: kt = [A]0– [A]
1st order : kt = ln[A]0– ln[A]
2nd order” kt = 1/[A] – 1/[A]0

k*30 = ln[0.500] – ln[0.319]
k = 0.0150
k*60 = ln[0.500] – ln[0.203]
k = 0.0150

reaction is 1storder, rate constant = 0.0150 s-1

The answer is b or dmost likely bhope it
