Interpretation:

To find out the concentration of X after 155 seconds.

Concept Introduction:

For second order reactions:

$\frac{\text{1}}{{\left[\text{A}\right]}_{\text{t}}}\text{=kt+}\frac{\text{1}}{{\left[\text{A}\right]}_{\text{0}}}$

where [A]_t, is the concentrationof A at time t, k is rate constant, t is time and [A]₀ is initial concentration of A.
