Question

Which of the following graphs are correct for a second order reaction?

[Symbols have their usual meanings.]

• A. (i) and (iii)
• B. (i) and (iv)
• C. (ii) and (iii)
• D. (ii) and (iv)

Answer 1

The correct option is B (i) and (iv)

For a second-order reaction, the rate law expression is, $Rate=-\frac{dC}{dt}=k\times C^2.$

Also, the half-life period is inversely proportional to the initial concentration.

Thus, graphs (i) and (iv) are correct.
