# Observe the following reaction : $2A +B \longrightarrow C$. The rate of formation of C is $2.2 \times 10^{-3}\;mol \;L^{-1} min ^{-1}.$ What is the value of $-\large\frac {d[A]}{dt}$ (in mol $L^{-1}\; min^{-1}$)?

$\begin {array} {1 1} (a)\;2.2 \times 10^{-3} & \quad (b)\;1.1 \times 10^{-3} \\ (c)\;4.4 \times 10^{-3} & \quad (d)\;5.5 \times 10^{-3} \end {array}$
