285435 For a reaction \(\frac{1}{2} A \rightarrow 2 B\), rate of disappearance of \(A\) is related to rate of appearance of \(B\) by the expression

1 \(\frac{-d[A]}{d t}=\frac{1}{4} \frac{d[B]}{d t}\)
2 \(\frac{-d[A]}{d t}=4 \frac{d[B]}{d t}\)
3 \(\frac{-d[A]}{d t}=\frac{1}{2} \frac{d[B]}{d t}\)
4 \(\frac{-d[A]}{d t}=\frac{d[B]}{d t}\)
