Question

Consider the following statements for the second order reaction, $2A\to$ products
1. The unit of the rate constant is $concentratio{n}^{-1}$ $tim{e}^{-1}$
2. $t_{1/2}$ is directly proportional to the initial concentration
3. The plot of 1/concentration versus time would give a straight line
Of these statements:

• A. 2 and 3 are correct
• B. 1 and 2 are correct
• C. 1, 2 and 3 are correct
• D. 1 and 3 are correct

Answer 1

Answer: (D)

1 and 3 are correct

The unit for the rate constant for a reaction of order $n$ is given by $concentratio{n}^{1-n}se{c}^{-1}$
