Multiple Choice

For the reaction A + 3B $\rarr$ 2C, the rate of disappearance of B given by ( $\Delta$ [B]/ $\Delta$ t) may also be expressed as

A) ( $\Delta$ [B]/ $\Delta$ t) = - (1/3) $\Delta$ [A]/ $\Delta$ t.
B) ( $\Delta$ [B]/ $\Delta$ t) = - 3 $\Delta$ [A]/ $\Delta$ t.
C) ( $\Delta$ [B]/ $\Delta$ t) = 3 $\Delta$ [A]/ $\Delta$ t.
D) ( $\Delta$ [B]/ $\Delta$ t) = (1/3) $\Delta$ [A]/ $\Delta$ t.
E) ( $\Delta$ [B]/ $\Delta$ t) = - $\Delta$ [A]/ $\Delta$ t.
