For the reaction A+BC+D, in an experiment with [A₀]= 400 mM and [B₀]= 0.400 mM the following data was obtained:

t (s)	0	120	240	360
[C] (10-4 M)	0	2.00	3.00	3.50	4.00

And an experiment with [A₀] = 0.400 mM and [B₀]= 1000 mM, it was obtained that:

t (ks)	0	69	208	485
[C] (10-4 M)	0	2.00	3.00	3.50	4.00

Determine the reaction rate law and the kinetic constant.
