View SolutionDuring the kinetic study of the reaction $2A + B \rightarrow C + D$,the following results were obtained:
Experiment $[A] \ (M), [B] \ (M)$ and Initial rate of formation of $D$ $i. \ [A]=0.1, [B]=0.1$ $6.0 \times 10^{-3} \ M \ s^{-1}$ $ii. \ [A]=0.3, [B]=0.2$ $7.2 \times 10^{-2} \ M \ s^{-1}$ $iii. \ [A]=0.3, [B]=0.4$ $2.88 \times 10^{-1} \ M \ s^{-1}$ $iv. \ [A]=0.4, [B]=0.1$ $2.40 \times 10^{-2} \ M \ s^{-1}$
Based on the above data,the overall order of the reaction is:
| Experiment | $[A] \ (M), [B] \ (M)$ and Initial rate of formation of $D$ |
|---|---|
| $i. \ [A]=0.1, [B]=0.1$ | $6.0 \times 10^{-3} \ M \ s^{-1}$ |
| $ii. \ [A]=0.3, [B]=0.2$ | $7.2 \times 10^{-2} \ M \ s^{-1}$ |
| $iii. \ [A]=0.3, [B]=0.4$ | $2.88 \times 10^{-1} \ M \ s^{-1}$ |
| $iv. \ [A]=0.4, [B]=0.1$ | $2.40 \times 10^{-2} \ M \ s^{-1}$ |
Based on the above data,the overall order of the reaction is:
For the reaction $2 NO_{(g)} + Cl_{2_{(g)}} \rightarrow 2NOCl_{(g)}$,when the concentration of $Cl_2$ is doubled,the rate of the reaction becomes twice the original rate. When the concentration of $NO$ is doubled,the rate becomes four times the original rate. What is the overall order of the reaction?
