Q. The initial rates of reaction $3 A + 2 B + C \to$ products, at different initial concentrations are given below.

Initial Rate, $M s^{- 1}$ $[A]_{0}, M$ $[B]_{0}, M$ $[C]_{0}, M$

$5.0 \times 1 0^{- 3}$ $0.010$ $0.0005$ $0.010$

$5.0 \times 1 0^{- 3}$ $0.010$ $0.0005$ $0.015$

$1.0 \times 1 0^{- 2}$ $0.010$ $0.010$ $0.010$

$1.25 \times 1 0^{- 3}$ $0.005$ $0.0005$ $0.010$

The order with respect to the reactants A, B and C are respectively
