• # question_answer 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) $\text{9}.\text{69}\times \text{l}{{0}^{-\text{3}}}$

$R=K{{[X]}^{2}}[Y]$
