Question

For a first order reaction, which of the following statements are correct? A. The half life are independent of initial concentration. B. The rate of constant has unit of \(s^{-1}\). C. The plot of \(\ln[A]\) vs. time is linear. D. A rate is independent of reactant concentration.

• A. A, B and C only
• B. A, B, C and D
• C. A and B only
• D. B and C only

Hint:

For a first order reaction, remember: \(t_{1/2}=\frac{0.693}{k}\), unit of \(k\) is \(s^{-1}\), and \(\ln[A]\) vs time gives a straight line.

Answer 1

The Correct Option is A
