Q.
The initial rates of reaction $3A + 2B + C \to$ products, at different initial concentrations are given below.
Initial Rate, $Ms^{-1}$
$[A]_0, M$
$[B]_0, M$
$[C]_0, M$
$5.0\times10^{-3}$
$0.010$
$0.0005$
$0.010$
$5.0\times10^{-3}$
$0.010$
$0.0005$
$0.015$
$1.0\times 10^{-2}$
$0.010$
$0.010$
$0.010$
$1.25 \times 10^{-3}$
$0.005$
$0.0005$
$0.010$
The order with respect to the reactants A, B and C are respectively
| Initial Rate, $Ms^{-1}$ | $[A]_0, M$ | $[B]_0, M$ | $[C]_0, M$ |
|---|---|---|---|
| $5.0\times10^{-3}$ | $0.010$ | $0.0005$ | $0.010$ |
| $5.0\times10^{-3}$ | $0.010$ | $0.0005$ | $0.015$ |
| $1.0\times 10^{-2}$ | $0.010$ | $0.010$ | $0.010$ |
| $1.25 \times 10^{-3}$ | $0.005$ | $0.0005$ | $0.010$ |
