For the reaction \[X+Y\to Z,\] following kinetic data was obtained :

Initial [X]M	Initial [Y]M	Initial rate M \[\mathbf{mi}{{\mathbf{n}}^{\mathbf{-1}}}\]
0.4	2.0	\[6.2\times {{10}^{-3}}\]
0.8	2.0	\[2.48\times {{10}^{-2}}\]
0.4	4.0	\[1.24\times {{10}^{-2}}\]
0.5	1.5	?

Calculate initial rate in the last experiment

A) \[\text{4}.\text{36}\times \text{l}{{0}^{-\text{3}}}\]                  

B) \[\text{5}.\text{81}\times \text{l}{{0}^{-\text{3}}}\]

C) \[\text{7}.\text{27}\times \text{l}{{0}^{-\text{3}}}\]

D) \[\text{9}.\text{69}\times \text{l}{{0}^{-\text{3}}}\]
