For a zero-order reaction, which option correctly gives the integrated rate law and half-life expression?

For a zero-order reaction, which option correctly gives the integrated rate law and half-life expression?

• A. [A] = [A]0 - kt; t1/2 = [A]0/(2k)
• B. [A] = [A]0 e^{-kt}; t1/2 = ln 2 / k
• C. 1/[A] = kt + 1/[A]0; t1/2 = 1/(k [A]0)
• D. [A] = [A]0 - kt^2; t1/2 = [A]0/(2k)

Answer: (A)
