Q.
For the reaction $A+B \rightarrow C$ ; starting with different initial concentration of $A$ and $B$ , initial rate of reaction were determined graphically in four experiments.
$3.2\times 10^{- 3}$
S.NO. $\left[\right.A\left]\right._{0}/M$ (Initial conc.) $\left[\right.B\left]\right._{0}/M$ (Initial conc.) $rate/M \,\sec^{-1}$ $1$ $1.6\times 10-3$ $5\times 10-2$ $10-3$ $2$ $3.2\times 10-3$ $5\times 10-2$ $4\times 10-3$ $3$ $1.6\times 10-3$ $10-1$ $2\times 10-3$ $4$ $3.2\times 10^{- 3}$ $10^{- 1}$ $8\times 10^{- 3}$
Rate law for reaction from above data is
S.NO. | $\left[\right.A\left]\right._{0}/M$ (Initial conc.) | $\left[\right.B\left]\right._{0}/M$ (Initial conc.) | $rate/M \,\sec^{-1}$ |
$1$ | $1.6\times 10-3$ | $5\times 10-2$ | $10-3$ |
$2$ | $3.2\times 10-3$ | $5\times 10-2$ | $4\times 10-3$ |
$3$ | $1.6\times 10-3$ | $10-1$ | $2\times 10-3$ |
$4$ | $3.2\times 10^{- 3}$ | $10^{- 1}$ | $8\times 10^{- 3}$ |
