34. Consider the following reaction and data measured at 25 °C:

2 A(g) + B₂(g) \(\rightarrow\) 2 C(g)

Initial [A] (M)	Initial [B2] (M)	Initial rate (M/sec)
0.10	0.10	0.18
0.10	0.20	0.36
0.20	0.20	1.45

When 1 mol of A and 1 mol of B₂ are added into a 1-L flask, the initial consuming rate of A (d[A]/dt) is x M/sec. The instantaneous consuming rate of B₂ (d[B₂]/dt) is y M/sec when 0.6 mol of B₂ is remained in the flask. Assuming the reaction proceeds only from left to right, what is the x/y ratio?
(A)41.7
(B)5.21
(C)8.33
(D)83.3
(E)16.7
