Ale. to me quien renction hate of reaction ( = )
[
begin{array}{l}
-frac{d[A]}{d t}=frac{-1 d[B]}{2 d t}=frac{d[C]}{d t}=frac{1}{2} frac{d C D}{d t}
-frac{d[A]}{d t}=2 cdot 6 times 10^{-2} mathrm{M} mathrm{s}^{-1}(text {Given })
end{array}

[
begin{aligned}
log +frac{d[A]}{d t} &=f frac{1}{2} frac{d[B]}{d t}
Rightarrow frac{d[B]}{d t} &=2 frac{d[A]}{d t}
&=2 times 2 cdot 6 times 10^{-2} mathrm{Ms}^{-1}
&=5.2 times 10^{-2} mathrm{Ms}^{-1}
&=text {option }(2)
