For a second-order reaction, the straight line among the following plots is

(a)[X] versus time

(b)1/[X] versus time

(c)$\log [\mathrm{X}]$ versus $1 /$ time

(d)$\log [\mathrm{X}]$ versus time

Answer

Answer: B ✓ checked by 4AB · confidence high

The source book printed no answer; this one was worked out and checked — see the explanation.

Explanation

Second order: 1/[X] = 1/[X]₀ + kt, so 1/[X] against t is linear.
