In a reaction $R \to P$,the concentration $[M]$ obtained at different times $(t)$ are shown in the following table. Calculate the average rate $r_{av}$ of the reaction.
Time $t$ $(s)$ $0$ $5$ $10$ $20$ $30$ Concentration $(mol \ L^{-1})$ $160 \times 10^{-3}$ $80 \times 10^{-3}$ $40 \times 10^{-3}$ $10 \times 10^{-3}$ $3.5 \times 10^{-3}$
| Time $t$ $(s)$ | $0$ | $5$ | $10$ | $20$ | $30$ |
| Concentration $(mol \ L^{-1})$ | $160 \times 10^{-3}$ | $80 \times 10^{-3}$ | $40 \times 10^{-3}$ | $10 \times 10^{-3}$ | $3.5 \times 10^{-3}$ |
(N/A) The average rate of reaction is calculated using the formula $r_{av} = -\frac{\Delta [R]}{\Delta t} = -\frac{[R]_2 - [R]_1}{t_2 - t_1}$.
| Time Interval $(s)$ | Average Rate $(mol \ L^{-1} \ s^{-1})$ |
| $0-5$ | $0.016$ |
| $5-10$ | $0.008$ |
| $10-20$ | $0.003$ |
| $20-30$ | $0.00065$ |
