Question

For a strictly second order elemental reaction $A \rightarrow \text{Products}$, which of the following specified graphical plots will yield a perfect straight line with a positive slope?

Answer: D

💡 Solution & Explanation

A is correct because $\text{Rate} = k[A]^2$, which is $y = mx$ with slope $k$. B is correct because the integrated rate law $\frac{1}{a-x} = \frac{1}{a} + kt$ matches $y = c + mx$, yielding a straight line with positive slope $k$. C is correct because $t_{1/2} = \frac{1}{ka}$, matching $y = mx$ with slope $\frac{1}{k}$ against $1/a$. Hence, all are correct.
