1st and 2nd set of data - No change in rate with the change in concentration of 'C'. 1st and 3rd set of data - On doubling the concentration of ' B' rate becomes double.1st and 4th set of data- On doubling the concentration of ' A' rate becomes four times.

Intial rate, $M s^{- 1}$	$[A]_{0} M$ ,	$[B]_{0}, M$	$[C]_{0}, M$
$5.0 \times 1 0^{- 3}$	0.010	0.005	0.010
$5.0 \times 1 0^{- 3}$	0.010	0.005	0.015
$1.0 \times 1 0^{- 2}$	0.010	0.010	0.010
$1.25 \times 1 0^{- 3}$	0.005	0.005	0.010
